Needs a torch for a dungeon quest, torches can only be purchased from the bull village shop. But if I go in there, the bulls chase me away. Did I do something wrong and I need to make a new game (because I forgot to save) I lost the first fight with the bulls. I am asking for help because this task blocks other tasks for me. Thank you in advance.

You need to meet thane and he (after some time) can make you a citizen of the bull village after you do some quests for his father (the chief). after you become a citizen you can go to the shop and buy the torch.
