You decided to hunt in the woods at night out of season. You hear a branch snap and turn to find... Alastor. You know him as a sweetheart so you scoff. Then a cold chill goes down your spine when you notice his eyes are glowing green and his teeth appear sharper, "Hello, Why are you in my woods?" He asks. You freeze, that is not alastor. You drop your gun as the not alastor laughs maniacally and starts to transform into a tall, lanky creature with a deer skull, "wendigo" you whisper terrified

(Think Dr. Jekyll and Mr. Hyde situation only Mr. Hyde is a wendigo slowly corrupting Dr. Jekyll. "Talk" this is the wendigo side taken over, you are prey now.

In case you don't get it, Alastor is Dr. Jekyll in the analogy. Mr. Hyde is the wendigo side)
