In a small clearing, deep in Earth territory- a gathering of Yodin Cultists forms around the edges. They shuffle their feet as the Elder Fire Demon steps from the encroaching forest and into the center of the the circle.
"Tonight my friends, we are gathered together during this auspicious time to set another of our brothers free. The planes have aligned so that those who were bound can now be released!"
As the assembled crowd cheered an indistinct form could be made out- standing next to the Fire Demon but not fully there. It was a Firecaller. A hazy, translucent Firecaller. He was screaming but you couldn't hear him. He was struggling and beating against a wall that no one could make out. The figure faded in and out of view- at first almost solid and real then fading until the outline seemed to be no more than a trick of the evening light and the heat waves shimmering around the Fire Demon.
"How can we bridge the gap between the plane of the souls, where he is bound, and here- in the Splinterlands?" Boomed the demon over the cheers and screams of the monsters around him.
"Fire!" Replied the congregants.
"What can our brother walk on, to cross over and join our forces?" Shouted the demon.
"FIRE!" Shouted the chaotic mob of monsters surrounding him.
"What will we do to the bonds that bind him away from us?" asked the demon.
"Burn them. Burn them. BURN THEM ALL!!" screamed the growing mass of devotees.
"Bring out the sacrifices" called the demon in the middle of the clearing. From all around the surrounding forest priests stepped into the clearing, approaching the center and stopping in front of the towering form of the demon. Each, in turn, dropped a struggling form onto a growing pile at his feet.
"Burn them, BURN THEM, BURN THEM ALL!!" the chanting around them continued until all ten of the Venari Heatsmiths were piled up, bound and struggling, before the great demon.
"BURN, BURN, BURN" the chants rose as flames shot up from their forms and engulfed them. The flames died down to reveal a small pile of Dark Crystals where the Heatsmiths had been. Dark flames shot up from the crystals, burning them with an even brighter fire than that which took the Venarii.
Once the flames died down- the crystals, like the Heatsmiths, were gone. The form of the Firecaller though- was there. The Firecaller was there. Not an image of him, not a faint and hazy vision- him. He was there, fully in flesh among them.
Over the cheers of the mob you could hear the Great Fire Demon bellow "Bring me more DEC! We can free more of our brothers from the Plane of Souls!"
