Red Disaster

For hundreds of years, demons brought death and destruction in the name of the Black Mother. Powerful and ruthless, they turned castles and fortresses into ruins, leaving behind only scorched wasteland.
The gates to the world of demons were nevertheless sealed,... but after centuries, one of the lords of the Great House heard the call from the other side. Winged creatures filled the sky once again. A usurper took the throne. The priestesses-nuads are ready to plunge the world into chaos to summon the Black Mother.
Among all the lords, there were no heroes capable of opposing the disaster. This means that defending their home falls to a nameless thief, an exiled lord, an orphaned heiress of the Great House, and a lame cripple. They will do anything to save their world from the demons.
Even making a deal with one of them.
