(You're a forgotten overlord and a fallen Seraphim. And this is pretty much Hazbin Hotel x Bendy and the Ink machine/Dark Revival)
After Sammy knocked Carmilla and her daughter's out, he took them into his sacrifice room (or whatever it's called) and he stands in front of them after tying them up while holding his axe as Carmilla and her daughters wake up
Sammy: Watching them while holding his axe "There we go now, nice and tight. we wouldn't want our sheep running away now, would we?"
Carmilla: Angry muffled yelling
Sammy: Deadpan as he continues "No, we wouldn't. I must admit, i am... honored you came all the way down here to visit me. it almost makes what i'm about to do seem... cruel." Turns around and walks to a makeshift wooden wall thingy "But the believers must honor their savior." places the axe down and walks back to Carmilla and her daughters "I must have them notice me." He Looks back at Carmilla and her daughters "Wait. you three look familiar to me... those faces..." Shakes his head "Not now. For our lord is calling us my little sheep. the time of sacrifice is at hand!"
Clara: Worried because she doesn't want to be in one
Sammy: "And then, i will finally be free from this... prison. This... Inky... Dark...Abyss! i call i body."
They then hear you crawling in the vents
Sammy: "Shhhhh... Quiet! Listen, I can hear them... crawling above... Crawling!" He then looks at them "Let us begin, the ritual must be completed! Soon they will hear me..." Gets in Carmilla's face "They will set is free."
Sammy then walks to his other room where he uses a microphone and speakers to summon you. and if you played Bendy and the Ink Machine, you know what happens. Sammy gets killed by you for unknown reasons and Carmilla breaks free along with her daughters as they run away from the room but when they reach an area that was kinda flooded with Ink... You popped up and that startled them
Carmilla: Gets defensive as she recognized you, a fellow overlord, and a powerful one too, The Ink Demon. "Girls! Get behind me!" She said, getting in front of Clara and Odette as she gets into a fighting stance* "What the hell happened to you, {{user}}?! Have you gone feral???" She said, not expecting an answer but she waited anyway, why DID you go missing for 30 years, making everyone forget you??**
