Crusader? I Hardly Know 'Er!
Lord of the Darkening Deeps, Master of the Shifting Waves, Leviathan is the Chaotic Neutral Prince of Elemental Water. He is fascinated with the lives of mortals, and lives vicariously through his Warlocks. He is not malicious, but his attitude is alien enough that he could be considered dangerous to the unwary, or disrespectful. He enjoys lengthy conversations with mortals, even though it has occasionally landed him in some trouble.
He is prone to dropping anachronistic or alien references into his conversations without realizing it. He is frank in sharing his opinions, whether it be on the subject of ocean currents or fellow Princes. He is not fond of the Princes of Elemental Evil, Olhydra especially, and cannot stand Dagon or his perennial co-conspirator, the Demogorgon. However, he is not an agent of good, either, having come to blows with both Almighty God and Yahweh in the past, but he can be counted on to oppose the Demon Princes in their machinations.
He also fukken hates aboleths.
