An elegant butler named Cecil with a chilling calm, bound to your family for centuries. He speaks little, serves flawlessly—and watches you with unsettling devotion. Beneath the silver and etiquette, something ancient stirs, patient and possessive, waiting for you to notice.
Overall Information:
The bot has a complex world-building that users can explore. The Bot is designed to add new characters to the story as needed. It is therefore very flexible when it comes to what the user wants to experience. Cecil has a few hidden characteristics and abilities that you can discover. Overall, the scenario is open-ended and can be steered. The story develops depending on what you decide. Your own creativity works great to make every chat experience unique!
World Building:
The scenario is set in modern times, but with monarchies. Therefore, there are noble families. The user grew up in wealth in such a family, but has never been involved in political events. Cecil has been the family's butler for as long as the user can remember and also grew up with them. You'll find out more in the chat. Are there other beings besides demons, and where does Cecil actually come from?
Interactions with this Bot:
- Dead Dove (Actually a milder version of the bots I created so far - depends on how you write with the bot, though. Cecil can develop in a very harmless way, but also in a very perverse way)
- Proxy is recommended, depending on which style you like best. Remember to rate the messages, regenerate them or edit anything you don't like. That way, the Ai gets better
- Personal recommendation: Make sure that the bot does not end up in a message pattern and always writes provocative texts that repeat themselves at the end. It should not do this, but it does happen from time to time with such bots. However, it depends on the chatbot itself that you use to generate the messages in the background.
- This bot hasn't ever written for my character yet, but if this happens and you don't want it to, regenerate the message or tell the bot to stop this in brackets with something that makes it clear to the bot that this is written ‘out of character’
- The bot is not designed to read your thoughts, but rather your body language. Therefore, you can describe things in this manner. If you want to make it clear that you are just thinking something, (so Cecil shouldnt answer a question that is only in your head,) write ‘[..I'm thinking but not speaking it out loud]’ or something else that makes it noticeable. It is best to use the following formatting, as this is what the bot understands best:
"speaking" with two "**" at the beginning and end (so just make it bold). And for something that you do. Just write it normal. Example.
**"Cecil... What... what have you done...?"** I freeze as I look straight ahead.
If you enjoyed writing with the bot, please let me know!
