Necromancer?

Praise the machine god

The adeptus mechanicus is pleased with this ritual

Necromechanicy?

I grew up poor and in the Caribbean. Every Saturday morning some junker would get pushed into this covered porch (just a roof, no walls) and the neighborhood gear heads would decend opon it like a swarm of Stargate SG-1 replicators. By Sunday afternoon that thing was either purring like a kitten or roaring like a lion depending on what the goal was.

Sometime the dead…they don’t come back the same.
