Extra-Dimensional

Description

The air inside the room seems somehow thicker, slightly more viscous. Outside shuttered windows, stars and comets cascade by, shining like a thousand diamonds against a swirling ethereal sky.
Requirements: A character or hireling that can cast 8th level spells
Construction Time: 30 days
Benefit: This room’s door is actually a portal to a pocket dimension, containing the room itself. The laws of time and gravity in the expansion are yours to set, within limit, only once when you first modify the expansion. Gravity can be half to twice as strong, and time can move at half-pace to double time, relative to the outside. The room also has the immunity to scrying, tracking, and similar that being located on a different plane provides.
