Firefly Glen But she knew.

Toad mirrored Miriam's laughter, though she didn't understand it. Toad nodded excitedly. In a sense yes; Osiris, Hydra's son, has decided to form a sister pack, Firefly Glen, she explained. Surely, Osiris had discussed this first with Neverwinter. Toad was unsure of all of the details though, and decided not to assume anyone knew anything. She was often out of the loop.
After talking to Dirge, she knew that there had been times that the Glen as a hunting ground had been contended. The family, and she herself, were most concerned about vagrants than they were neighbouring packs from the sounds of it. It made sense then to ally with those that they would be sharing a border with. Recently one of our puppies went missing, and there've been all sorts of vagrants troubling us, so it made sense to have more security for everyone's sake, Toad went on.
She knew that at the very least, securing the Glen would prevent such people from bothering Neverwinter as well. Ideally, the entire valley would be coated in wolves in the correct side of law and order.
