WWT (white winter tiger) at first I didn’t know who on God’s green earth Rorin was, but I like the story! So how about these ideas

Storm made a bargain with the death worms that they could kill Rorin if it left others alone.

Someone starts hunting Rorin (like my hunters, Henry and Alex)

Rorin goes back home, but Storm has convinced the others apart from fluffy to try and kill him
