Spawning Trees

Demons beget demons. Where their filth lands, they spawn ever more corruption.

— The Cartographer

Treelike growths cluster along the shoreline of a lake of bubbling, black goo. Each growth is formed from the same ichor as the lake and has writhing, membranous sacs budding from its limbs.
Lakes of demonic ichor appear where demons are slaughtered in great numbers. Malformed trees grow on their shorelines, their branches laden with fleshy sacs. These eventually flop to the ground and wetly break open, each one releasing a fully grown abyssal chicken.
