Khalgor technically but it's not really him. just the nameless showing you your wildest dreams lmao Orgram has nothing whatsoever atm.
no, you can't win the fight against him, its fixed as you play Groth instead of MC so your stats won't allow you to prevail. also, as I said it's the nameless scene, if Orcs like you enough it shows Khalagor and all the other red orcs pounding your brains out for a second. like he does with all the other things.
