It's funny you are not the first one to say that. I have never played castlevania so I don't really know, I might have been inspired by image before but it wasn't intendeed.
Was mostly inspired by the cainhurst castle in bloodborne (https://i.ytimg.com/vi/y4xih32QV40/maxresdefault.jpg) but I think it was itself inspired by the Castlevania so in the end it takes the same root (I mean it is called the damn castle of cainhurst and it was the resting place of the vileblood who are pretty much vampires )
Considering that aberrants are my favourite type of monster I might try to make a one shot based on this idea - thx for the inspiration! o/
