Dortomortis

This is Dortomortis (very creative name), an old myth that is rarely talked about anymore. But if you see him at the top of a mountain... you better get ready. He may not seem very threatening, but he never hesitates to swing his sword, not feeling anger, remorse or anything of that kind. Only emptiness fills him and his victims, who he throws off mountains when he is done with them... And now the fun part; You! Yes, you there. You're probably wondering what you're doing on top of a mountain. Well... he brought you here in your sleep (through ways of plot) and now you either fight him or die by his hands... since he can't exactly... die (or maybe he can, idk, y'all can do some wild stuff ;) So yeah have fun
