Spectre

Fall [I] — "There were ravens all around, he could hear them. The forest was lifeless. The trees dead. The grass brown and dry. He had never felt more at home."

Spring [I] — "Spectre had just gotten back from a walk when the pup ambushed him from behind. He knew what was coming, it was the same thing every day since she'd been adopted into the pack.
'Spectreeeee, did you see me coming? Did you?'
'I didn't see anything. Promise,' he answered with a straight face.
'Can you tell me the story yet? You said I only have to get just a biiiiiit older before you'll tell me. That was yesterday. Now I'm older.' Gale rambled on.
Spectre gave a long suffering sigh.
'Okay, okay, I give. I'll tell you the story at sundown. Come find me then.'
Gale's eyes went wide; she'd been bugging him for weeks.

'A long, long time ago, in this territory, there was a lone wolf. A wanderer. He came to call this place home. That all changed on a foggy night. He awoke to pawsteps, right outside his den. He thought it was odd, that a wolf would suddenly appear, after months of not seeing a soul. The fog thickened with each step. It was coming. Closer, and closer. Now, being a somewhat brave wolf, our wanderer sprang from his den. He was hoping to surprise the intruder, but that's not what happened at all. No, when he landed, he landed on the forest floor. Above him, the ghostly shape of a wolf was waiting. Watching, through clouded blue eyes. He tried to speak, but his voice was different. It was muffled, like he was swimming in the river. The wolf leaned in, and whispered.
'Get out of my forest.'"

Nobody knows where Spectre really came from, or how a blind pup even got to the territory alone. Or why Blackbird had that look on her face when she brought him to the pack.
