Bahlthizar's Private Board

You create a extradementional doorway in an unoccupied space that leads to a room that is 50ft wide, 50ft long and 20ft tall. It is fully furnished and can comfortably sleep 10 humanoids. It also comes with provisions reminiscent of a home-cooked meal and can be whatever the caster wishes. The provisions can feed up to 10 humanoids three times a day. When the spell ends, anyone and anything brought into the room is shunted out within 10ft of the casting point.
