The Red Demon

"Let me make things clear. I am more than a god. I am the end and the unspoken of. You are here because I willed it to be!""The Red Demon, to Zenaxus during The Agreement"The Red Demon is an unknown entity that exists in the Sabre of Meitor campaign. He has shown to be an antagonistic force, although his true powers and motivations remain unclear...

A Magical Ability
The Red Demon could be seen by the Heroes of Time during their trip to Ashmarsh, chained within the pentacle at the heart of the village.

However, when the murder occurs, the heroes decide to enter the pentacle to prove the innocence of the suspect. They unwittingly break the ancient magic holding the beast chained. Giving an almighty roar, the beast disappeared and the party appeared as demons to the villagers, who then turned on them...

The Agreement *SPOILERS*
After Zenaxus died during the Festival of the Shadow Winter, The Red Demon struck a bargain with the half elf. In return for destroying the final pentacle, the one in Liken, Zenaxus would be granted his life and a place at his side. Zenaxus accepts but is defeated by Bramble the Brutal almost as soon as his resurrection is complete.
