Ygorl is the slaad Lord of Entropy.



Ygorl appears as a blackened, bat-winged, skeletal hulk, wielding a large scythe.


As one of the exemplars of the chaotic neutral alignment, Ygorl is not truly evil, but still very dangerous, unpredictable, and self-serving. He believes in bringing death, decay, and disorganization to the multiverse, and thinks this is best done by the slaadi, the truest agents of chaos.

Abilities and traits[]

Ygorl's fortress in Limbo constantly changes appearance; it can be a rough cavern, a shattered marbled temple, or a series of interlaced carved spheres that whirl through Limbo's layers.[1]


Ygorl considers the slaadi to be his living pawns. They do not serve him in any organized fashion, but most will obey his orders rather than allow him to devour them.


Ygorl rides a great wyrm brass dragon named Shkiv. Ygorl is also allied with Sorel, his lieutenant, whom he is grooming to become the Lord of Anarchy.

Of the other slaad lords, he enjoys the company of Chourst, at least at times.


Ygorl ignores fellow slaad lord Ssendam and fears Rennbuu.


Ygorl is the second oldest slaad lord, after Ssendam, and is considered the de-facto ruler of Limbo. He is said to have created the Spawning Stone that is the focus of the slaad race, forcing them to take frog-like forms rather than their original, purely chaotic shapes.
