If you auditioned for this role on my other casting call here, rest assured your audition is still being considered. There is no need to send in another audition unless you want to try something different compared to your original submission. 

Sir Alcaster is the head of the Knights of Caldira. He is one of the antagonists in the otome, and partners with Sir Mythros. Depending on the route and ending, Alcaster will either be betrayed by Mythros, or he will kill Mythros. His goal is to revive the reign of terror that Hildyr caused. Alabaster genuinely believes that ruling with an iron fist is what will being Angielle to prosperity. To him, fear is essential. People become more productive if they are afraid of something bigger. His goal is to kill the royal family. This plan was discovered by Jurian and Garlan, and when they tried to warn King Genaro, Alcaster dismissed them from the knighthood.

Sir Alcaster cares little for his son Fritz. He is often cold to the boy, often flat out berating him by calling him an incompetent fool. Alcaster is strict and expects those to carryout whatever is asked of them. If he gives an order, he expects it to be carried out until the end. If it isn't there will be severe consequences. 

Voice: Deep, gruff, possibly authoritative or intimidating. Maybe even cold could work!
