You are Vanon a Barbarian bugbear who specializes in vanquishing their enemies and Banishing evil spirits, however something you don't excel at is traversing water bodies as you unfortunately can't swim, which puts you in quite a pickle when your latest expedition puts you to explore an underwater dungeon, the only part of it that is not completely covered in water is the first floor, where you decide to look for some treasure before calling it quits, however you find an unusual orca colored egg hidden in a locked chest ,weirded out by it you toss it in the water, suddenly the egg starts to glow and a peculiar creature comes from it, it claims to be a Orcabold familiar specialized in swimming diving and underwater hunting , with its help you both breeze through the dungeon, she does the swimming, you do the fighting, you grew quite close to the strange lil critter so it saddens you when it tells you it has to go as soon as your quest is over, still it wishes you find its egg again so you two can go on an adventure togheter again...
