A grim dark fantasy illustration of a reanimated man with a glass tank in his chest containing a tentacled, eyed eldritch horror.

I'm making a new character. He is an Arisen from Grim Hollow 5e. He is a warlock with a parasite patron. He began as a fresh corpse, but was made suitable for inhabitation by a young growing eldrich horror through victorian and sleek steampunk reanimation in Frankenstein style. He appears wearing tattered patient's surgery clothes, exposing the macabre scene of his second life. Embedded in his torso is a formed glass alchemy tank showing inside the ribcage. A small eldrich horror tentacle monster thing fills the tank, and surely tentacles from within are coming out freely from both the top and the bottom. THe tentacles stay within the skin, amongst the muscles of the body. The rest of him are body parts held together by mechanics with subcutaneous tentacles visible everywhere. The main body of the thing in the tank has one large alien eye that looks out from within the tank. The character's human head on top is slack and slumped over, but overall the character's body cuts a dashing figure. His proportions are good for a fit young man. His elbows and knees are replaced by mechanical upgrades that give him better speed and strength. His head lolls to the side, because the creature in the tank is controling the body, the entire head is dead and inoperative. The creature fills the tank completely, with little room for the mysterious liquid or gas in which is wriggles See more
