Gather the Black Acolytes
Magic-User Spell Level 3
By the drawing of certain lines and curves, the caster slips into an extra-dimensional space, leaving a creature from another universe in his place. The caster can't know or control the type of type of creature, and the creature will vary from once casting to another. The caster appears in a special dimensional space—a space also occupied by anyone (or anything) else that cast the spell during the same time. It's a sort of meeting room. The caster may choose to return his original location after either three minutes, three hours, or three days.
