"Banish the darkness," he says, and drops a single drop of holy water into the cauldron. "Banish the darkness," and he drops the Communion bread then. "Make me a tool to banish the darkness of this world."

"Banish the darkness," Willow intones after that last part.

Theo is not sure whether to repeat that or not. He decides not to, unless either of them hints that he should, since he hasn't spoken during the ritual at all yet.

He doesn't hint.

"Take this offering, that it fuel your power." He drops one of the crystals into the cauldron. The cauldron sizzles, and the lights start flickering. "Take this offering, that it fuel your power." Second crystal, more flickering. He stirs the cauldron twice with the crucifix-ladle, and intones, "Banish the darkness, with the power darkness cannot stand. Channel through me the power of the sun."

"Banish the darkness."

Again, Theo won't say anything unless he gets another hint.

The special effects are nice. Kinda worrying, but nice.

Sadde switches to Latin, and chants some rhyming verses as he drops the remaining crystals, and then a few other strange powders. Soon the light goes out altogether, but by then the bubbling liquid inside the cauldron is emitting its own light, as are Sadde's eyes.

Oh, okay. That's not creepy at all.

Are Willow's eyes okay? How about Theo's own? He can check by seeing if light reflects off his a hand in front of his eyes, if he has to.

Willow's eyes are fine. She has stopped chanting, and now is only waving the sage about in silence.

Well, he assumes his eyes are fine in that case.

He awaits further... anything.

Given that he doesn't speak Latin, it'll probably look mostly the same, with the occasional "Banish the darkness" here and there. Until:

"Goddess Hecate, hear my plea. Use me as your vessel, take me. I offer you my being and my soul, that you may cast destruction upon those who taint the earth. Banish the darkness."

The liquid starts swirling on its own, with blotches of brighter light here and there, and the diamond he left on the table starts glowing.

Well. That sounds potentially worrying. Obviously he doesn't interrupt it, because that could be dangerous, but. 'I offer you my being and my soul'? The bit after that makes it sound better, but still.

A few more verses in Latin, and the liquid swirls, swirls, swirls, until it's more gas than liquid, more aether than matter, and Sadde says: "Goddess Hecate, make me your tool, accept this symbol of destruction and be the stake through the heart of darkness!"

He then drops an actual stake into the fluid, which becomes a jet of light, going through Sadde's heart and leaving from his back before entering the glowing diamond. He screams, facing the ceiling, his eyes glowing white, the ex-liquid piercing him without leaving an actual wound.

Um okay that really does not. Sound. Good. Willow? Any help here? Is this a normal thing that he should be ignoring and wasn't warned about and okay why wasn't he warned, this is potentially the worst prank ever!

Willow has stopped waving the sage about and is now watching. She does not seem particularly pleased about it, but neither does she look terribly alarmed or surprised.

Well, right, in that case Theo will just quietly freak out over here. At least it's presumably a thing that's supposed to happen.

Aaaugh.

Eventually all the fluid has gone through Sadde and into the diamond, and he slumps forward, using the cauldron for support. The lights come back on, and no more special effects seem to be happening. He's breathing heavily, though, as if he's just run a marathon with a bear trap on each leg while fighting an anaconda. With pneumonia.

...yeah, he doesn't look too good.

Theo moves slowly forwards, and (unless Willow stops him), makes his way over to Sadde to see if he's okay. Should he get some water? Does Sadde need food? Is it just a temporary thing? It would be nice if they had told him more about this.

No, Willow goes with him, and helps support Sadde.

Who will lean heavily on her and, should he elect to help, too, Theo. He grabs the diamond and says, "Living room, yeah?" His voice's shaky and somewhat weak, reflecting some of aforementioned exhaustion.

Yes, Theo elects to help.

"Sure," he says, sounding a bit relieved that Sadde's at least not unconscious. This magic thing definitely does not sound very fun. Was Sadde trying to scare Theo away from it? Because he might've succeeded.

He flops onto his couch, clutching the diamond in his hand, and leans his head back.

Willow looks sorta resigned, and sits on the couch, too.

Theo sits on the other side of Sadde from Willow, a comfortable distance away but not crowding him. "Do you... need anything?" he asks.

"Just rest. Willow can probably help you with books while I do."
