You trace the outline of a door, and a shimmering portal appears, leading to a space accessible only by you and your allies.

Daily   ✦     Arcane, Conjuration
Standard Action      Melee touch

Effect: You conjure a spacious extradimensional dwelling that can hold up to fifty Medium creatures. It is reached through a single doorway that you trace on a surface or in the air. Only you and those you designate can pass through it. You can close the entrance and make it invisible after you enter the mansion, and only someone inside the mansion can open the portal once it's closed. The mansion contains comfortable furnishings and enough food and drink to satisfy its denizens. The furniture and food disappear if removed from the mansion. The mansion lasts for 8 hours, and any creatures still in the mansion when the power ends reappear in unoccupied squares outside the entrance portal.
