Thaumiel: The God Killers

Heroes: people of legends, strong, powerful, much more than mere mortals. Those who are sent to vanquish evil, to save the world of Thaumiel when it is threatened.
You'd expect someone sent to kill a god to be the most powerful person to ever exist, right? No god has ever been killed by a mortal before.
However, instead of a powerful being with skills unknown to any, what this legend has is a naïve half-elf knight, a wood elven witch disguised as a barmaid, and a demonic exiled assassin with an ego.
It's a damn good thing they have a god helping them with this.
