Fortress Siege

Survive the demon invasion and find the way to banish them forever.

Dark days are upon your land; twisted people have made a pact with demons, hell gates have been opened, and demon kind has started to roam this world. As time passes, more hell gates open and the demon army grows stronger and bolder. If they are not stopped, the realm will be overrun.

Your scholars speculate that if there is a ritual to summon the demons then there must be the one to banish them. Help them perform the ritual and defend them from demons who will try to stop them.
