Yes! Your amorphous form pours forth from the hellmouth and slurps noisily to the concrete floor of the basement of a small suburban home. As you finish the assembly of your amoeba-like body and the last of your power slips through to inhabit the shell, the hellmouth snaps closed behind you with a muted pop! Six of your eyes open and you gaze about at the frightened mortals before you. Their expressions register horror and confusion as their limited minds attempt to comprehend your divine majesty. One mortal cries out as his sanity flees to the deepest recesses of his mind. He begins to babble incessantly in an ancient language which you recall from years past, speaking of your coming and the wonderful things you will accomplish. He speaks of your dominion over the world, and sacrificing all unbelievers to your everlasting divinity.
You draw yourself up tall, a whirling amorphous chaos of confusion with uncountable eyes and appendages forming and subsiding as they are needed. You are powerful and vital and alive. You are Clar-... er.. Yuiller! Three of your mouths open to sing the song of your coming, the sound cracking the concrete floor and shaking the modest dwelling above.
Your Calling completed, the energies that brought you into this world now fade and silence descends upon the scene.
Suddenly from above you hear the phlemy voice of an elderly mortal female, "Francis! Keep it down your father is sleeping! You said you and your little friends would be quiet!"
The summoner who brought you into this world draws back his hood, revealing the adolescent face of a teenager pocked with acne. His eyes flash annoyance. "Mom we're busy!", he shouts, and then quieter to the teenage cultist next to him who has also removed his hood "God... she can be so annoying."
Something isn't quite right here. You expected some kind of... well... temple. Maybe a ritual circle at least. Usually there is ram's blood or a virgin or.. something. I mean you're no expert, you've only been doing this for 17 millennia, but still... they're just kids. How did they even find the power to bring you here, or knowledge to perform the Calling? Something smells fishy here... aside from you that is.
While you are still trying to make sense of this, the Summoner steps forward. You are shocked to realize that he is exuding no fear pheromones at all! And there isn't even a ritual barrier between you and him! In fact, extending your aetheric senses, none of the cultists have any protection whatsoever... though you are picking up a faint trace of power from the now-insane-and-babbling-hysterically cultist who is currently staring at one of the cracks your Coming song has created in the floor. He might have some potential, but these other kids are as empty as most mortals. You have no idea how they managed this, and you really don't like not knowing things.
Speaking of knowing things, what precisely are you the god of oh magnificent one?
