While reading tons of Head-related posts, two thoughts I have often contemplated come to mind.
1) The Head sent Alric in search of a suit of magical armor buried somewhere in the Barrier. Since Alric felt so betrayed, I always assumed the armor search was a wild goose chase. Indeed, Alric never speaks of it or searches for it again. He's probably embarrassed about being tricked. Anyway, I think the armor is a hoax concocted by The Head, or at least it was nowhere near the Barrier.
2) Ever see that picture of Balor sacking Muirthemne in Myth II? He has his helmet off and he's bald and ugly. Now look at him in the Myth I cutscene before "Pools of Iron". He seems young and has black hair blowing in the wind. (He's still ugly, but he sure doesn't look the same.) Now I personally believe this is a Bungie error. After all, how could we expect those overworked guys to be 100% consistent all the time, especially factoring in limited time and many different artists? But if we are to take everything that appears in the final version of Myth as universal truth, Balor has some explaining to do. Did he get reconstructive surgery? After all, he's on his second life and I wouldn't describe his old self as stunning. (If so, he has terrible taste in faces. If you're the most powerful, malevolent being in the world you can at least get yourself a satisfactory face. Why not be devilishly handsome or menacingly hideous? C'mon Balor, get yourself a fashion consultant or you'll never amount to anything.)
Seriously though, Balor may have used many bodies, or even have been two people. The door's wide open. Please state your opinions on the matter.
