Slayer

On Pagan, the Slayer is a story to scare children. A weapon with a mind of its own, which would long for the wearer to spill blood so that it could be fed? However, the Slayer is by far no story. It is very real. Stored in the old ruins under the East Road, it only waits to finally feed again, to again tast the blood of its victims, of the smited foes.

The Avatar accidently stumbled into the whole thing, when he broke through the ground of a old ruin at the East Road. Following the advices old old books through the ruins under the ground, he at the end found this bloodthirsty weapon.

It is unknown what happened to it, after the Avatar left Pagan.
