Not quite a lone wolf, Adder kept mostly to himself in the Aernis Mountains. He had left his home pack in search of his own fortune when his father died and a wolf he did not get along with stepped into the alpha role. He made sure to put a fair bit of distance between himself and the pack. Adder and an older acquaintance, Bearclaw, would often hunt together when they craved larger prey and her knowledge of herbs was very helpful when he found himself crawling with mites. When the bright-eyed Mist happened upon him one day, he saw her potential at once. He asked humbly to join her tiny pack and offered the services of his friend. Mist was keen to have a healer alongside and agreed at once to meet with Adder and Bearclaw. Later that day he sniffed her out and together with Morrow, the Stinging Nettle pack was born.
A friendly forest pack, Sprucerain, requested Adder's presence for a short time to help train up some strong chasers. He was more than willing to help out.
Added by Moonwatcher: After he came he found himself playing with the pack's pups. But he saw something that made him stop. He realized 1 of the pups was blind!
