Incomprehensible quest

There was a quest to bring 5 skins of polar bears to some NPC from the brothers of the storm (I don’t remember the name). And extra. The task for him is to steal 5 skins in the Qing Grove. There is a girl there and she has a label for this quest. I stole a pickpocket but there was only one and then extra. The task failed. Is it worth bothering at all? And if so, what to do?
