Challenge: Grimbark

It may seem impossible that so small a creature can have so large an impact on the world, but it is the case that the small insects driven to madness by the caretaker of the woods of Agamaur are such creatures. Grimbark has long held control of the Arboretum at the behest of the Red-maid and with his corruption has driven all living denizens of the swamp mad.

Description
Stage 1

The Huorn Grimbark is lost to the corruption that has long plagued this land. It is an unfortunate end for a once noble creature, but Grimbark cannot be redeemed.

You are tasked with destroying Grimbark, but you should avoid harming the bees under his dominion.
