In Thornmar Abbey, an ancient order of holy knights watches over a sealed portal to the underworld.

The knights must protect the elders—ancient sages who sustain the seal.

After decades of peace, the seal has weakened and demons are emerging from the rift.

The demons seek to battle past the valiant knights and kill enough of the elders to fully break the seal before morning. Imbued with the power of the gods, only these brave knights stand a chance of protecting the elders and stopping an army of monsters from flooding into the world.
