"I am Sharak, the Judge. The innocent have nothing to fear, but the guilty will get their just punishment."
Sharak is the God of Justice, and the patron god of all judges, guards, watchmen, Meddlers and others who uphold or enforce the law. He oversees all laws, both written and unwritten, natural and of societies, magical and mundane, and he also has the power to enforce them if necessary; any verdicts he passes are final and nobody but the Dragon or the Serpent can argue or go against them.
As Sharak considers all oaths, verbal or written, as unbreakable laws, he's also the god to swear by for those who wish to make an oath or declare their complete truthfulness about anything; Sharak's name is synonymous with reliability, and any oath given in his name is considered unbreakable and absolute. (It's said that those who choose to break an oath given in Sharak's name risk the wrath of the god himself.)
He is steadfast and uncompromising, has no tolerance for even the slightest bending of any rules, and several people have hinted that he may be a little too uncompromising and more concerned with punishing those he deem guilty than protecting those he deem innocent. It was Sharak who, back when the world was created, demanded the banishment of Vanadys, and the two have never reconciled since then.
Still, while he often comes across as stiff-necked and inflexible, he is also fair and just, and holds himself to even stricter rules than he holds anyone else to, and he looks with disdain on people who seeks to exploit laws for their own gains, or try to get around laws via loopholes or imprecise wordings.
