Blades - Admiral Alvarez on Antigua (note there is a bug with him, in that he will not offer to train you any further if you have told him you have all the Titan Artifacts. The only way around this is to load a previous save).
Alright, i dont have any training options from him and i still havent done the Slayne quests yet.
So i guess i dont have all the artifacts yet but still he doesnt have any dialouge options for training.
Thanks to KillerBEA for the artwork
