7th-level Spell: Echo Chamber

Dream Magic (Conjuration)

You tap into the Wilds of Limbo, summoning forth an Echo of a dwelling in range that lasts for the duration. You choose where its one entrance is located. You can choose to have the entrance appear as a portal, a door, or as a curtain, but each shimmers faintly, revealing it as supernatural in nature. The entrance is large enough for a Medium-sized creature to comfortably walk through. You and any creature you designate when you cast the spell can enter or exit the Echo as long as the entrance remains open. You can open or close the entrance if you are within 30 feet of it. While closed, the entrance is invisible.
Beyond the entrance is a dwelling of Heart, Draelish, or Wildling origin (your choice). Roll 1d4 to determine the state of the summoned Echo:

The place is appropriately furnished and decorated as governed by the condition in which it was pulled from Limbo and contains enough food for 10 people to eat a sufficient meal from. The size of the space is determined by the condition it is in. The space can't exceed the total size given, but can be divided up into multiple rooms or portioned off sections (as determined by you or the GM). If the space beyond is glimpsed (whether through a crack or window), it shows nothing but a void below and a strange night sky above.
Furnishings and other objects created by this spell dissipate into smoke if removed from the Echo. When the spell ends, any creatures or objects inside the extradimensional space are expelled into the open spaces nearest to the entrance.
