Any way to easily fetch these?
Login in on Armageddon.org.
Click the button and choose biographies.
I don't think it gives access to all characters, but I could be wrong. Lots of mine are omitted and I'm not sure why.
What Armaddict said. It will show you all bios and descriptions for all of your characters (to my knowledge).
If you played before 2005ish those characters won't show up.
