God-Slayer
God-Slayer (known to his few friends as Prince Yuri Barkov Daniel) is an OC from Total War: WARHAMMER. He is the former Kislevite noble who went to save Ursun, yet instead of saving him he got corrupted and twisted by Chaos. By the time he came to and meet Ursun, he was twisted to the core by Chaos and shot the bear god with a enchanted bullet that supposedly killed Ursun. Because killing a god is serious business, and the fact that he didn't choose a patron, he got turned into a (second) Daemon of Chaos Undivided by all four Chaos Gods for aforementioned killing of Ursun... who was revealed to be still alive, but in the hands of Be'lakor, who is definitely planning something. Thus God-Sla...Daniel gathers his forces to finish the job.
Unlike Be'lakor, the God-Slayer can say fuck it to the whole "Undivided Prince" gig and become the Blood-Sprayer, the Couch-Layer, the Ball-Drainer, or the Lie-Sayer...or mix and match body parts how he likes resulting in some really BIZARRE FORMS.
History
He was a human once. Prince then, prince now. But jokes aside, Yuri Barkov (not Kovalenko, as some lore grognards hoped) was an Ungol prince that was tasked by Tzarina Katarin herself to find Ursun. You see, in TWW continuity (at least for now) Bear-God ended every winter with his powerful roar. But then he disappeared, and Kislevite climate, which was already harsh, became pretty similar to the Game of Thrones one. To end the the seven years-long winter, Yuri with his brother Gerik and some warriors marched north, to the Kislev's northernmost outpost Dervingard, where Ursun was last heard.
The road was hard and filled with various dangers, and many considered quitting even before reaching the outpost, but then Yuri received a message from Ursun, who told prince that he is still very much alive and needs saving. So, Kislevites marched north, but faced many problems.
