Description: Merrshaulk is the yuan-ti deity of Poison and Somnolence. “Merrshaulk” is likely a dwarven rendering of his name; the yuan-ti pronounce the name more like “Mi-Shao-Shur,” although they view it as too holy to pronounce around outsiders. Merrshaulk manifests as a vast yuan-ti abomination with a male human head and stubby forearms. He has begun to decline into slumber, spending years barely conscious within his snake-infested Abyssal pit. The yuan-ti have declined with him; they believe they can awaken him, however, with enough sacrifice and acts of depravity. Then he will shed his skin and devour the world.
Relationships: Merrshaulk is a variation of the World Serpent archetype, like Shekinester, Io, Jazirian, and even Ramenos. He considers Jazirian to be his archnemesis. His relationship with Tlaloc, the patron of Olman yuan-ti, is unknown.
Dogma: Merrshaulk encourages competition within each caste in order to ensure that only the most qualified leaders come to the fore. Every act of gratuitous cruelty and suffering committed by the yuan-ti brings the Sleeping Serpent closer to awakening. The more ingenious the plan, the more power it brings. The more intelligent beings hurt and traumatized, the better.
Only gratuitous evil helps awaken the Sleeping Serpent. If the evil brings tangible benefits to the yuan-ti (other than pleasure), it only brings those benefits. Protecting their lairs or finding food are important, but for them to be sacred they must do more. Therefore, the atrocities committed by the yuan-ti are not selfish in nature. They murder, desecrate, and undermine governments. The fact that they love doing these things is incidental.
The yuan-ti religious code forbids them from harming other reptiles, however. They need not lay down their lives for reptiles, but they cannot eat or otherwise harm them. They abhor cannibalism.
Worshipers: Merrshaulk is revered by yuan-ti, ophidians, and some spirit nagas who have rejected Shekinester.
Clergy: Of all yuan-ti, only the Shan-Pachan, the human-headed yuan-ti abominations, may become priests. In addition, priests of Merrshaulk are exclusively male. They must be skillful ambushers and defenders of lairs.
Temples: Temples of Merrshaulk are typically made of dark stone or caverns beneath the earth. They are lined with columns depicting serpents devouring humanoids, or of humans transforming into serpents. In the center are pits of writhing snakes.
Holy days: The Sagacious Slumber is a month-long period of hibernation in the middle of winter, immediately preceded by an orgy of eating. Immediately following the Slumber is the Shedding, in which the yuan-ti shed their skins while sacrificing intelligent beings to their god. The Shedding is followed by a period of particularly energetic activity.
