Aside from some interesting tidbits, I saw mentioned 'Malahk-Orcs' and how they made Orsinium Orcs look like pansies. Supposedly they lived in the hills of Morrowind.
Now, i'm playing Morrowind through at the moment, and aside from somehow stumbling on Shrines of Malacath -three times- in one in-game day and having to slay/run from hordes of Orcs i've seen no sign of any sort of tougher and meaner 'hill Orcs'. Stll, are these perhaps the ones he is talking about? Or just something that never made it into the games? Or could he perhaps be talking about Ogrims?
