The character
This individual boasts a grasp over their subjects that dwarfs the idea of an "iron first". With an infallible moral compass nudged only by personal perspective, they are the main head of law in the kingdom. Every royal figure has their story, and with every story comes rumor... and it goes without saying that this king is the most about business. Barely a moment of their waking hours isn't spent polishing the law (or enforcing it). Rarely does a day go by where the rumors of their bravery do not become enforced. In the face of the toughest situations or the most daunting of tasks, no-one is as efficient as he.
Campaigning on the idea that order and loyalty are the most important part of a kingdom, their faction provides the largest military force for the kingdom. In support of their words, this is not because they simple have the largest population- rather, their effective leadership strategy caused a whopping 70% of their kingdom to answer the call to arms. Thusly, their species makes up the largest section of the kingdom's fighting force... and they won't let you forget it.

The voice
The voice for this character was a difficult one to place. With a large cast, differentiating every voice came down to exaggerating a few key characteristics: And this one may not be kind on the throat.
The voice we're looking for is a coarse one. A dry, judging tone is optimal, as one that sounds on the verge of anger at all times while carrying that sand-like coarseness will do well for a vast majority of their interactions. 

P.S.
We may already have a voice for this role, but the character is open for audition just in case this just so happens to be someone's specialty.
