This spell is a part of the Graveyard's Warding spell chain and can be found in the Graveyard's Warding rune stone.
The zombie is perhaps the most honest expression of what The Worm is. No pretense of purpose, no echo of the person it once was, no dignity held over from whatever life it used to have. It is simply flesh that The Worm has decided to keep moving. It is animated not by will or intent but by the same hunger that drives all of The Worm's work, the refusal to let something simply stop when there is still use to be gotten from it.
When the seniumancer casts The Rotting Dead they reach through The Worm and drag one of these things into the world beside them. What rises is exactly what it appears to be - a body in some state of decomposition, moving with the graceless determination of something that has no capacity to be afraid, no capacity to hesitate, no capacity to do anything except what the hunger that animates it demands. It serves the seniumancer not out of loyalty but because The Worm serves the seniumancer, and the zombie is nothing more than The Worm wearing a body.
The seniumancer may have active zombies equal to their Influence trait at any one time. Each remains until it is destroyed or the battle ends, at which point The Worm lets the flesh fall and returns to the seniumancer, satisfied with whatever use was made of it.
For the zombie's full capabilities, consult the bestiary.
