Gupunuul

A River Drake named Gupunuul has dwelt in this cavern for nearly 2 years. She’s careful to limit her hunting to the Cursed Fens so no one in Engleher knows she exists.
She was out hunting when the Passing Hand thieves came through, but she returned soon after and cut off their easy escape route (leading to their eventual capture by the Morlocks).
Gupunuul is likely to be sleeping in the water in the middle of the cavern, and she swiftly wakes up if she hears the splashing of potential food swimming above.
The drake is aggressive but not suicidal; if reduced to fewer than 10 Hit Points, she flees and doesn’t return for a few days. She pursues foes that flee To the boat launch or out into the swamp, but she learned the hard way about the dangerous mold at the beach and won’t pursue potential prey there.
