Thessarak

Religous fanatic of the abyss

The serpent named itself Thessarak, the Coiled Prophet, and launched into a fanatic rant about needing to spread the love of his lord throughout the sun-blessed creatures on the surface, largely ignoring the ballistae and spells striking him.

As the fight at the manor wound down, an enormous serpentine creature rose out of the Abyssal Gorge, visible from the Valecourt courtyard across the city. The wall's fortifications came online in response, throwing up a barrier as magic and artillery flew between the two.
