The Devourer

The Devourer is a giant (or from The Necromancer's perspective, small) Cthulhu-esque squid that will eat literally anything, and can evolve as a result. This is your main goal of the game, and dictates the pacing; along with what you want to merge.

While anything can be given to The Devourer to eat (except for final gravestones and the Necromerger), you mainly want to feed it monsters that give it lots of food, which is the equivalent of experience points.

When trying to feed the Devourer a station, you will be prompted by a confirmation screen. It is for this reason that you won't have to worry about accidentally destroying it.
