Spidrens are a fearsome race of Immortals which resemble a giant spider with a human head.

Spidrens hunt at night, because their webs glow in the dark. They subsist by eating animals and humans. When fighting humans or other Immortals, Spidrens wield weapons including axes.

Though intelligent, the Spidrens are intractably vicious and no humans have been able to make peace with them.
