Nyaka/Necromancy/Communicate with Undead/Call

Call Undead
Allows casters to call an undead entity that still resides in the world to appear within the prepared circle. The caster may also call back departed from the other side, but this is much more difficult. To call someone back requires a sacrifice normally consisting of rare and expensive herbs, potions, incense, and/or artifacts, that are burned, consumed or otherwise destroyed during the ritual. No matter the sacrifice, no target is forced to appear unless they want to. If the target has been reborn, or is so far beyond that it has become unreachable, the spell fails.
