@Takegami As far as I know, Pious Emperor is the title Gumi gave Alza Masta, the title he was given by Karna in JP was "TeiShinKou" this is where I got that information from;  https://www.reddit.com/r/bravefrontier/comments/6q8e1t/lore_spoilers_some_notes_on_alza_masta_and_2_of/

@Tofu420 I don't think Lucius had any involvement between the conflict of the Masta brothers. It never said that Lucius was Karna's disciple, as Velma had that honor...which perhaps she was the very first disciple Karna ever had. For the Imperial Gods' lroe I don't think Lucius was mentioned even once
