In the subterranean spires of the Yuan-ti, empathy is considered a genetic rot, a vestigial weakness of the 'lesser' races. Sslithas was born with this 'defect' in abundance. As a scion of a powerful smuggling house, he was expected to calculate the overhead of human misery. Instead, he felt the psychic resonance of every lash and every chain. His rebellion began in the shadows of the 'Veins of the Earth,' the secret trade routes of his kin. He began replacing crates of prohibited spices with political dissidents, spiriting them away under the cover of night. He was eventually found out, not by a slip in security, but because he was caught weeping over a dying slave he couldn't save.
Exiled and hunted, Sslithas fled into the Great Parched Expanse. During a month of record-shattering drought, he climbed the Peak of Broken Glass and screamed at the silent heavens, demanding mercy for the thirsty. The sky answered with a localized typhoon that nearly took his life, but in the heart of the storm, he saw the truth: the lightning does not strike to kill, but to bridge the gap between heaven and earth so the rain may follow. He emerged as the first priest of the 'Gentle Gale,' founding the Cloud-Gatherers to bring down the Sultan who hoards the desert's few remaining wells.
