You create a shadowy door on the target. The door is large enough for Medium creatures to pass through. The door leads to a demiplane that appears as an empty, 30-foot-cube chamber made of wood or stone. When the spell ends, the door disappears from both sides, trapping any creatures or objects inside the demiplane.

The entity sends forth a servant loyal to it to aid you in your endeavors. If you have a specific servant in mind you may speak its name during the casting, but ultimately who is sent to answer your call is the entity’s decision. 

The target must remain within range for the entire casting of the spell (usually by means of a
