This is an old character when I used to DM....IT started out a rich,spoiled young man who wished to be strong...Strong as the Heroes of legend! He went to seek power in the remote keep of A Mad Wizard,who fooled him into volunteering his humanity to his Dark Arts...
His Younger sister,worried when after 4 years he still hadn't returned,hired a group of Adventurers to investigate his diappearance...The GOOD Group(consisting of mainly LGs & Paladins)freed IT from the Dark Wizard's spell but His intelligence was reduced to an almost animal level....If IT's sister hadn't come along,The Adventurers might have met their end...As it was,His sister Andrella spent 10 years searching for a way to restore him to normal,His mind slowly repaired itself....Leaving her a goodbye note,IT went to the Far Reaches where IT became a Bodyguard for the Khanate's 16th daughter,Shirenane(that's her)....She's not a Princess,but that what IT calls her(And When you've got Strength of a Storm Giant,who gonna Argue with you)?!
