Brogud, the Deathless One

I am working on flushing out my major character, Brogud, the un-killable living god of the orcs. this book that i'm working on, All Shall Rest, details his struggle against hordes of undead under the Putrid Legions and coming to terms with his own standing as a God. my cousin and colleague Chuck asked some good questions regarding not having Brogud be too badass and shit, so i am working of flushing him out plenty, especially since i will be using him in other books as a cameo, "oh shit who the fuck was that dude who just saved the main characters or did something else equally important?" type scenario.

So far, i have that Brogud was born a long long while ago, so much so that even he has problems remembering his origins. Because he is incapable of death, he has had lots of time to get fairly good at pretty much anything he has wanted to master, such as the practice of Magic, Martial Arts, Weapon-Mastering, research into different fields, ect. Because of his agelessness, he also suffers from OCD to a small degree, and is very scatterbrained, often working on many projects at once, which are also dragged out over time, mostly because his concept of time is growing very askew. He is starting to notice a strange set of instincts, a sort of 'knowing' that he cannot explain, what he is calling his "God-sense." Brogud does not enjoy praise, even though he is worshiped by many savage Orc tribes, the natives of the Bear Islands, and others scattered around Thegorn and the rest of the world. the Orcs of his native tribe and those under his command during the Purge Wars do not 'worship' him per say, but make sure to give him respect and blessings at their shrines to their other gods. as far as physical power and prowess go, however, he has few flaws, being considered the greatest warrior to ever live, for good reason, seeing as how during the Purge, he killed many powerful undead warriors who had bested many Thegorn champions, and slaughtered more undead warriors than anyone, even holding off an entire horde of Zombies with the help of only a Dwarven warrior. he has a very powerful sword from an ancient age (rumored to have come from the Stars) that will mold itself to any sword or combination of swords the wielder requires, Brogud preferring a huge, single-edged greatsword, dual sabers, and a short gladius-style blade. He practices with any and every weapon at every opportunity he can get, and hosts bare-fisted prize fights in the village he exiled himself to.
