Thantis

Thantis, the Warweaver is a legendary spider from an unknown plane.

History
A monstrous web of burning mana spreads across a distant forest, inciting rage in every creature that stumbles into its tangle. As these creatures seethe and struggle, they become food for Thantis, a giant and malevolent spider. The fury of her prey feeds her own ferocity before she feasts on their corpses.
