High Colonel Dias 
leads Granorg's army in the videogame Radiant Historia. Both him and Count Selvan are the tertiary antagonists in both the original and alternate timeline of said game. Dias is the first major villain that Stocke, Raini, and Marco confront when he appears at a bridge in Lazvil Hills; but the outcome turns disastrous when he sends Palomides the Executioner to finish them. Raini and Marco don't make it out alive and Stocke is forced to jump off the bridge and ends up in a cave. With the help of the White Chronicle and the Guardians of Historia, the fateful encounter never happens and Raini and Marco's lives are spared. Dias is one of the few people that seem to know the purpose of having a former commoner, Queen Protea, on the throne.
