It is actually from an old cartoon samurai jack there was this evil dude demongo but i misheard his name so i started using demango basically the origin is very childish and boring so i won't go in depth
My characters
oblivion
I originally played as a Khajiit rogue but i got bored quickly the i tried a Dunmer rogue of which i got tired even faster then a few mages and finally a Redguard warrior which is my current main and of course i recently started a Breton mage (who i created basically just to get in the imperial library :P)
