Adder

Adder is a dark shadowy-brown tom with yellow eyes and a slightly twisted muzzle from an old injury on his face.

Summary
Adder is the leader of a rogue band a few days' journey from AshClan's forest. When the journeying cats finally arrive to his territory, looking for one of the herbs to cure the chilling disease, two strange cats warn them to stay away. The journeying cats ignore the cats' warnings and push through Adder's territory. Adder reveales himself, and he threatens to kill them all unless they leave. The journeying cats refuse, and a brawl ensues. During the battle, Adder is killed, causing the rogues of his band to scatter.
