Emil, the Vampirate

I've been concepting an RPG where the player awakens as a recently turned vampire and quests to take down the one who bit him. Emil here would be the main character, a pirate at sea who fights with a handheld ballista and magic. The game would involve seeking out certain party members and managing to keep the general public or even your own party unaware of your vampiric nature as well as battling a hunger system that may make the player attack mortals that they're in dialogue with. I've concepted quite a few potential party members that have different goals and stances on vampirism that would effect how the game is played.
