- I repeat: will presume you are using the Great Wheel Cosmology
In reference to expanding this Room ‘s Dimensions ; you could theoretically make a series of 30×30×30 Demiplanes lined up future to each other in any direction, then good rip their barriers apart to connect them ; a brawny adequate caster could probable perform this without excessively much campaign. Phlogiston is what technically makes the creature/object ethereal and provides omnidirectional movement ( 2 disjoined effects ), if you are paying attention you will recognize the chemical reaction to “ willpower ” ( Intelligence, Mental Fortitude, Mental Prowess ). strong intelligence when visiting the Deep Ethereal using Demiplane Spell will give you a stronger/faster character amidst the Phlogiston .
- Possible to connect these rooms? Yes.
- Easy to connect these rooms? Nope.

I am going to pull from my gathered information listed in this Stack Exchange doubt over here to answer your original question very quickly so far highly thoroughly, though inaugural I will preface a few things :
- I will preface stating I presume you are using the Great Wheel Cosmology
- Mordenkainen’s Magnificent Mansion doesn’t expand space, this would actually get Conjured, unlike the Demiplane, you wouldn’t die from this, just a regular portal to a temporary pocket dimension.
- in the Deep Ethereal (movement, breathability, travel)
- from “Phlogiston” (D&D equivalent of “Space Ether”, AKA Protomatter)
- No, you can’t merge the Doors (you would require multiple mages to cast 4× anyway)
- You forgot Squeezing, you should actually update your question to reference “No Elephants” as opposed to “No Ogres” because Ogres (& donkeys) could squeeze their way past this door.
immediately, onto my chief bulk reference quotation to help thoroughly answer your original question ( I looked at this question ‘s Edit History ), again ; presuming you are using the Great Wheel Cosmology :
page 48 in the DMG reads :
ethereal flat :
…
The Ethereal Plane is a brumous, fog-bound property. Its “ shores, ” called the Border Ethereal, overlap the Material Plane and the Inner Planes, so that every location on those planes has a match placement on the Ethereal Plane. Visibility in the Border Ethereal is limited to 60 feet. The plane ‘s depths comprise a region of swirling mist and fog called the Deep Ethereal, where visibility is limited to 30 feet .
Characters can use the etherealness while to enter the Border Ethereal. The plane shift while allows transport to the Border Ethereal or the deeply Ethereal, but unless the mean finish is a specific location or a teleportation traffic circle, the item of arrival could be anywhere on the plane .
Border ethereal :
From the Border Ethereal, a traveler can see into whatever airplane it overlaps, but that flat appears muted and indistinct, its colors blurring into each other and its edges turning bleary. celestial denizens watch the plane as though peering through distorted and frosted glass, and ca n’t see anything beyond 30 feet into the other plane. conversely, the Ethereal Plane is normally invisible to those on the overlap planes, except with the help of charming .
normally, creatures in the Border Ethereal ca n’t attack creatures on the overlap airplane, and frailty versa. A traveler on the Ethereal Plane is inconspicuous and absolutely silent to person on the overlap plane, and solid objects on the overlap plane do n’t hamper the motion of a creature in the Border Ethereal. The exceptions are sealed charming effects ( including anything made of charming effect ) and living beings. This makes the Ethereal Plane ideal for reconnaissance, spying on opponents, and moving about without being detected. The Ethereal Plane besides disobeys the laws of gravity ; a creature there can move up and down equally easily as walk .
deep aeriform :
To reach the Deep Ethereal, one needs a airplane shift go or arrive by means of a gate spell or charming portal site .
Visitors to the Deep Ethereal are engulfed by roiling obscure. Scattered throughout the plane are curtains of diaphanous color, and passing through a curtain leads a traveler to a region of the Border Ethereal connected to a specific Inner Plane, the Material Plane, the Feywild, or the Shadowfell. The color of the curtain indicates the flat whose Border Ethereal the curtain conceals ; see the Ethereal Curtains mesa.Read more : Top 10 phi hành gia mới nhất năm 2022

Traveling through the Deep Ethereal to journey from one flat to another is unlike physical travel. distance is meaningless, so although travelers feel as if they can move by a simple act of will, it ‘s impossible to measure amphetamine and hard to track the enactment of fourth dimension. A trip between planes through the Deep Ethereal takes 1d10 × 10 hours, careless of the origin and finish. In fight, however, creatures are considered to move at their normal speeds .
From this Data we found :
The Ethereal Plane besides disobeys the laws of gravity ; a animal there can move up and down ampere easily as walk .
additionally, this supernumerary information prevents certain results : effort to attempt to destroy Walls gets limited from :
distance is meaningless, therefore although travelers feel as if they can move by a simple act of will, it ‘s impossible to measure speed and unvoiced to track the passage of time .

Cosmology: Great Wheel
In the Great Wheel cosmology exemplary, the Ethereal plane existed adjacent to the Prime Material Plane and connected it to the Inner planes ( the Elemental planes plus the Energy planes ). The Ethereal touched the Prime at all points that were located within crystal spheres through what was called the Border Ethereal. It was strange whether the Border Ethereal touched the Prime in the phlogiston quotation : 6 citation : 13 .
The non-Border area was called the Deep Ethereal. While in the Border Ethereal, a traveler could still see into the adjacent plane but merely pallidly and not identical far, whereas those on the surround plane could not see the traveler without charming detection. verbal communication was not possible between the Border Ethereal and the bound airplane. The Ethereal was singular among the many planes in that an individual could exist in two planes simultaneously : the Border Ethereal and the adjacent plane citation : 6 .
When travelers crossed into the Border Ethereal, they and all their possessions were converted to their Ethereal equivalents—metal became ethereal metallic element, flesh became aeriform human body, and so on citation : 14 —allowing free motion ( in most cases ) in any steering through the hearty matter of the adjacent plane citation : 6. Since everything was permeated with ethereality, an air-breathing creature could breathe aeriform air and could not drown in an ethereal lake nor be crushed by an aeriform rock. however, not all in the adjacent airplane was insubstantial. Living things larger than single-celled animals generated an aura that radiated around them and prevent passage to their interior, so an ethereal traveler could not place a weapon inside a surviving creature where it would materialize and cause damage. A jungle would be an highly agonizing tangle to navigate ; it would be much easier to float above the vegetation or pass below its roots. dense metals such as lead or gold besides prevented passing of aeriform matter. And finally, some charming spells and alchemic mixtures could form an effective barrier citation : 14 .
travel in the Ethereal and Border Ethereal was accomplished by force of will—you wished to go somewhere and you did, at your convention rate of bowel movement. There was a sense of up and down but no real gravity existed. Objects released from possession would hover where they were dropped ; it was impossible to fall in the Ethereal plane citation : 15. To get to another airplane, one had to pass through a curtain of miasmal coloring material into the Deep Ethereal, then traverse that region until reaching the curtain that demarcated the Border Ethereal of the destination airplane. Each Inner plane and demiplane had a curtain with a unique semblance. The Prime Material flat ‘s curtain was turquoise quotation : 14. If the ( normally charming ) ethereal effect wore off while a traveler was in the Deep Ethereal, he would immediately be forced through a random curtain at a random location in the Border Ethereal and deposited on the plane which it bordered Citation : 15.Read more : Top 14 nhận định mới nhất năm 2022
When you passed through a curtain into the Deep Ethereal, time slowed devour to one one-tenth the rate it flowed in the Border Ethereal and the plane that it bordered. For every ten hours spent in the Deep Ethereal alone one hour passed on the other side of the curtain. Metabolic and other natural processes slowed down besides, so it did not feel like ten-spot hours, when you crossed back through a curtain into a Border Ethereal you were only an hour previous and an hour hungrier quotation : 14 .
The Deep Ethereal swirled with large blobs of protomatter ( imagine a cosmic lava lamp ) which could form a demiplane when a critical size was reached. knock-down wizards, technologists, or demigods could besides bend the proto-matter to their will and create a demiplane citation : 16. These nascent planes might exhibit some of the characteristics of the Inner planes or the Prime, but with their own rules of gravity, material makeup, and so forth, and even support liveliness. Most demiplanes finally collapse into themselves and break up or merge with another Inner or Prime Material airplane citation : 17 .
