Gronk sees the mixture of awe and uncertainty on everyone's faces, something he is used to seeing as a professional stage performer, and decides to continue with his work.
"For my next trick, I will make this mist-" he gestures to the mist thickening around them- "disperse with only the strength of my will. A moment of silence, if you please."
When the audience falls quiet, Gronk begins to concentate, eyes closed. After a long pause, he picks up a challace on the table and takes a large gulp. (The challace contains the quicksilver necessary for the ritual). As liquid fire courses through his body, he begins to glow a faint but perceptible light, and the space around him feels tense, as if magically charged.
With another flourish, the flaming bowl shoots higher than before, Gronk adds a new ritual vessel to the flames to contain new magic components. To this bowl, he adds a dash of quicksilver from the challace, and he begins a rhythmic chanting. The language is strange and cannot be understood, even by Gronk, but the sound is primal and feels like it resonates through the space and adds structure to the tension. After a few moments of chanting, Gronk picks up the ritual blade on the table, swishing it deftly from hand to hand in a form of ritual dance designed to honor the blade and the tradition surrounding it. All eyes are captivate on this man dancing and chanting in the fire light, when he lets out a scream louder than before. The knife glints as it slices through the darkness, leaving a short, jagged gash across Gronk's forearm. The blood that drips from this wound is collected in the ritual bowl for several moments before Gronk bandages his arm with a grimace.
"An offering to the spirit who will be my lovely assistant for this one," Gronk adds by way of explanation. In a booming voice, he intones, "Come forth, Obscurios, and be bound by my magic. Enjoy the feast that I have set for you, and lie in readiness for my command."
An eerie feeling creeps over the table and the nearby audience. The tension feels thicker, more sinister, as Gronk resumes his chant and dance as before. Within a minute, the scent of his blood fills the air, mingling with the smell of smoke and quicksilver. The fire grows continually higher, without any assistance from Gronk, until it threatens to engulf the whole table in flames. Gronk is sweating from the heat and the exertion, and his sweat falls into the ritual bowl as he works. At the height of the ritual fervor, an inhuman screach fills the area, mixing with Gronk's own shriek. The fire extinguishes, silence falls across the clearing, and Gronk lies motionless on the floor for a moment. After he recovers slightly, he raised his hands, still lying down, and says, "Ta-da...." His hands fall back and he rests for a minute.
