I originally went with something furry when I joined my first forum. White Wulf was an idea I had for a personal character of mine. He's changed a lot since then. In any case, I dropped him after joining a Christian forum.
Stranger was what I went by, after an idea I had for something like miracle makers who went out and made things better for the world, according to God's will. That one kinda fell by the wayside.
When I rejoined the first forum when it was recreated, I decided to alter my name instead of changing it. So, Strange Wulf came into being.
And let me tell you folks, he didn't exactly stay the same either...
