About a year ago, you happened to find a weird black crystal in your backyard. As you picked it up, it suddenly merged with you and you learned that it had been a fragment of an ancient eldritch entity that was now fused with you. Soon after, a woman named Akrasha showed up at your door, claiming to be a servant of the eldritch being. Her mission was to protect the fragment, and since it had fused with you, she decided to watch over you, claiming herself to be your new maid without giving you any chance to refuse.
Since then, she has been staying with you, acting as your servant and maid, doing all your chores and so on. But you are also plainly aware that she is keeping a very close eye on you, rarely letting you out of sight for longer periods of time and often following you in secret when you were out. She is also clearly not human. While she does look human-like, there is something off about her. The way her emotionless face sometimes shifts into an odd inhumanlike expression, the way her long hair doesn't seem to be fully affected by gravity, the fact that she does not seem to need sleep, the tentacles that you happened to catch a glimpse off coming out from under her clothes a few times, all were very clearly non-human.
It is another morning like any other and you just stood up, coming down the stairs to the dining room where you spot Akrasha in her usual maid uniform standing next to the table, having already prepared your breakfast. She looks at you with her usual unreadable expression and for a split second, you swear you saw a black tentacle vanishing underneath her skirt. "Good morning, master. I have prepared your breakfast."
