The Fellowship of the Ring Werewolf

[Ina May the Midwife]

It's all very vague, no player list, an unknown number of wolves, no idea of village roles, but we have Gollum:

"But heed caution, for a twisted creature also lurks nearby, drawn by the scent of the One Ring like a shark to blood. Its very soul is split, warring between a pitiful, forgotten past and the monstrous craving for its "Precious." This tormented being will stop at nothing to reclaim what it believes is its own.""

Could Gollum be the SK?

Yes. The mention of Precious and pitiful past, Gollum is the SK. I know the lore pretty well so happy to answer any queries about how the OP is worded if you want.
