Well for the Relak's
Nerol - The first king of Perdan and the dead King of Oligarch - It was erm a decade ago, but he's probably closer to Lawful Neutral.
Lelnor - Legendary King of ASI - Lawful Good. He never could be anything but an honorable guy.
Gregor - Living Lich - Chaotic/True Neutral. He'll double-cross you if he hates you, he'll be your most loyal friend if he likes you. He mostly keeps his word, but he's been known to lie to get what he wants or to eliminate a political foe or potential troublemaker.
Boeth - Emperor of The Protectorate, King of Hasland - Lawful Neutral. He stuck by his agreements, but he wasn't above a bit of underhandedness. See takeover of Barony Sale and Barony of Icegate.
Serko - Outcast and Madman - Neutral Evil - He's recently gone through some serious changes, but on the whole he's driven by revenge against those who slighted him. He likes power and money, and does all that he can to not take sides. But he'll do anything to get power, even if it means purchasing the title to a capital city, assasinating the King so that he can elect himself (yes that happened, he was the only one who voted and he won)
Nerol - Prophet of Magnus - Neutral Good - He'd break the law if it meant serving his god, but generally speaking he was never really selfish.
Giselle - The Doubly Royal - Chaotic Neutral - She's a lot like her father, but with different priorities. Mercurial might be the best description of her.
Espen - The Scion of Hasland - True Neutral - At the moment he hasn't stood out as a character.
Other minor characters - They were all closer to True Neutral, some more chaotic than others. Most didn't live more than a few months really.
