Ursun
Ursun, the God of Bears and Strength, is the patron god of Kislev and Gospodar especially. Almost always depicted as a giant brown bear, sometimes with a gold crown, claws and teeth, but is also portrayed as a large burly man with grey streaks in hair wearing a loincloth and carrying a spear sometimes. He has no temples, but instead is worshipped in special gardens or bear caves. Has a rivalry with Ulric, but it's mostly friendly and is about competition for more blessings.
He was unseen earlier, like most other Gods, but Total War: WARHAMMER revealed Ursun as a giant (much bigger than Be'lakor in the cutscene) polar bear with glowing eyes.
Total War Warhanmer 3 (aka Ursun the Bear in Distress)[edit]
Turns out the dying god mentioned in TWW3 promotion campaign is Ursun, chained by Chaos. The Kislevite prince Yuri Barkov rushed to the North Pole to save him, but was corrupted by the Big Four and decided to shoot him right in the heart with a demon pistol. Ursun was severely wounded, but then that asshole Be'lakor stole him and chained him again, now in the Forge of Souls, so Be'lakor could use the energy from the god’s death to become the chaos god of shadows and the souls of the people who try to rescue him to make an army of soulgrinders. So it seems that the mighty protector of Kislev is just a play toy for pretty much everyone (which is infinitely more embarassing than Tzeentch's imprisonment of Sigmar).
Search for the Ursun is the main goal for every faction in the game. Cathayan Dragons are searching for him because he know where their missing sister Shen-Zoo currently is, both God-Slayer and Skarbrand want to kill him, first to eventually ascend to Godhood and the second to get forgiveness of Khorne. Kairos wants Ursun's eyes to give him the ability to see the present on top of the past and future he already can, and Ku'gath wants his body to create plagues able to infect and kill gods. N'Kari wants to experience Ursun die before him to savor the moment. The Kislevites want to rescue him in order to stop the endless winter killing their land and people, and as prophesied by a 4chaner the Ogres indeed want to eat Ursun, in order to savor god-flesh and have the greatest feast of all time and feed whatever is left of him to the Great Maw.
And then he dies. In every ending. He is killed by Be'lakor and used to regain physical form, power him up and help create even more Soul Grinders. And although in Kislevite endings Ursun is ressurected through faith, Bear-God is still very pathetic in TWW3 continuity and doesn't do a damn thing.
