Origin
Sivart was born in the Blackmire. Or found himself there. Or was left there. He does not know which and does not care. A flooded fungal wetland deep in the swamplands south of Secomber, canopy so thick the sun hits the water maybe an hour a day. No clutch. No colony. No parents he ever knew. Just a small yuan-ti hatchling, alone in the root structures of massive cypress trees, sleeping in hollows, eating shelf mushrooms and whatever he could catch with his hands. The swamp raised him. The fungus fed him. And when a starving snake-child prayed to anything that would listen, the only thing that answered was the rot beneath his feet.
He didn't choose the spore gods. They chose him. Or at least, that's how he tells it. He watched a dead tree consumed by bracket fungus over the course of a season and saw divinity at work. He pressed his palm flat against the soil and felt the mycelium threading through it: the nervous system of something vast, something that had been thinking long before anything with legs showed up. If all consciousness is one network experiencing itself through fungus, then what is all this? The walking, the fighting, the building of kingdoms on dirt that will eat them. Why does any of this monkey-brain lizard-mammal business matter? He developed rituals before he had language. Bows to rot. Kneeling before mushroom blooms. A whole theology built from observation and hunger and the desperate need to believe something was listening.
He found a community once. A small colony of yuan-ti monks living on the edge of the Blackmire, where the bog meets drier ground. Not proper yuan-ti society. Outcasts, exiles, quiet folk who had chosen stillness over ambition. They took him in. Taught him to speak. Gave him his first name, something serpentine he doesn't use anymore. An old monk named Vassk showed him the Way of Mercy: how to channel the stillness between breaths into something that could hurt or heal. How to coil, how to strike, how to lay hands on the dying and push death back one more hour. It was not a grand monastery. It was a handful of old snake people on a dry island in a wet world, practicing patience as a form of worship.
But Sivart already had a worldview before the monks found him. The spore theology was in his bones by then. So when the Way of Mercy met the gospel of decomposition, what came out was something neither tradition would recognize. He heals because the cycle demands it: you are not done yet, the network still needs you. He kills because the cycle demands that too: you are done, the network is ready for what you become. The monks tried to correct this. They were gentle about it. But Sivart was already cooked. The mushrooms got there first.
Two of the older monks never trained. Never cooked. Never did much of anything useful, as far as Sivart could tell. They sat on the edge of the temple platform all day with their feet in the water. One of them, Kahss, played an old gourd banjo that hummed with a resonance no instrument made of gourd and sinew should have. The other, Drenn, played a jaw harp made of bone that vibrated in frequencies Sivart could feel in his tongue. They played together for hours. Not performing. Not rehearsing. Just feeding something in the air that Sivart couldn't see but could feel. When Kahss noticed the young snake watching from the water, he held out the banjo. "Sssit down," he said. "The roots are lissstening."
The monks were already old when Sivart was young. No drama took them. No blight, no war, no collapse. They simply aged. One season Vassk didn't wake up. The next year, Drenn's hands stopped working and the jaw harp went quiet. Kahss played alone for a while, then he stopped too. They didn't reproduce. There was no next generation. Just fewer voices in the evening, fewer feet on the platform, fewer lanterns lit. Sivart buried each one according to spore rites: no cairn, no marker, just returned to the soil where the mycelium could find them. The last one took forty years to play out. When it was done, Sivart was alone on an empty platform with a magic banjo, a bone jaw harp, and a mask carved from bog oak that was taller than he was.
The mask. It had been in the temple before the monks arrived, mounted on the wall like something between a door and a warning. Taller than any yuan-ti, carved in a style nobody recognized. A face that was not a face. Hollow eyes, a mouth full of carved roots, the wood darkened by centuries of Blackmire damp. The monks had prayed in front of it without knowing what it was. When Sivart was the last one standing, he took it down and wore it. It fit against his body like armor, hollow side against his chest, the face staring out over his shoulder when he slung it on his back. He wears the banjo in front of it. The mask behind, the music ahead. Whatever the mask is listening for, the songs are the answer.
Decades passed. Sivart stayed. He watched generations come and go in the Blackmire. He knew the tortles before Moss. He knew Moss's predecessor clutches, saw them hatch and age and return to the mud. He was already old when a particular tortle showed up, alone, building cairns for the dead and praying to gods that were not the spore gods but felt adjacent. The tortle offered him soup. Sivart watched him reach back and scratch the crusty, dried funk off the underside of his own shell and crumble it into the pot for seasoning. Sivart ate it. It was one of the worst experiences of his life. But the tortle was kind. And Sivart sat by that campfire for the first time in years and wrote a song about him.
Then things happened in the swamp. Strangers came through. An adventuring party, loud and bright and violent in ways the Blackmire had not seen in a long time. Sivart watched from the waterline, two green eyes above the surface, as Moss got swept up in something larger than the bog. He watched the tortle leave. He did not follow. He wrote it down. The swamp was quieter after that.
What Sivart wants is simple. To be left alone. To watch. To sing praise and worship to the fungus in his little zone. He has seen enough of the world to know it does not need his help. The mycelium connects all things. The cycle returns all things. If people could just see that, if they could just stop with the building and the fighting and the wanting, they would understand what he has always understood. But they don't. They never do. And that is the part that keeps him up at night, half-submerged in black water, playing a banjo for the roots: he can see the entire network, feel every thread, hear the vast slow thought of the thing beneath the ground. And nobody else seems to notice. Nobody else seems to care. He has been preaching to the swamp for sixty years and the only congregation that shows up is fungus and frogs.
He travels now. Not because he wants to. Because the spore gods, or whatever they are, keep sending people through his church. And every time someone walks through the Blackmire, Sivart watches from the water and writes a song about them. Every song is an offering to the cycle: you lived, someone noticed, the song outlasts you both.
