Homunculus is a tribe of allies in Shadow Era.
They were introduced in Dark Prophecies, with further support in Shattered Fates. This type of ally are made up of creatures which have been artificially created by their specific faction (they have members on both the Human and Shadow sides). They seem to have a wide range of effects, some involving the graveyard, discarding, and attack/health increasing.
