Pureus' father is a man who harboured a family knowing the oaths he was breaking by doing so, having lost his wife after his second son was born to execution by High Justice Vaylin, he took it upon himself to see that one or both his sons would become fierce and unstoppable Knights of Zakuul the likes of which the order hadn't seen since Arcann and Thexan had their rise.

But he becomes consumed by this goal so much that he forgets vital qualities of humanity in his sons which leads to one them being banished. Pureus deeply resents his father for this and believes his mother's memory is actively being disgraced.

This character was inspired in large part to Tywin Lannister in HBO's Game of Thrones (Performed by Charles Dance) Here is an example if you are unfamiliar with that character: https://youtu.be/7who4CaKl14?si=Zw00FpN2FMKsNLLB&t=118

This is the type of performance I would be looking for or something close to it with Pureus' father.
