You dare soil my home after what you've done below?! I will watch you dissolve before I suck down your liquid forms!
Umbrasyl, upon being confronted by Vox Machina in his lair[6]

Umbrasyl, the Hope Devourer, was an ancient black dragon and a member of the Chroma Conclave. As an NPC, Umbrasyl was portrayed by Matthew Mercer.



Umbrasyl was an ancient dragon with black scales.[7]


Umbrasyl had been hunted enough from lair to lair that he wanted an environment where he could rule without worry of being bothered or assaulted by people who wanted to be rid of this black dragon scourge.[8]

Little is known about Umbrasyl.

"Omens" (1x39)

Umbrasyl was first seen by Vex, Vax, and Grog as a black blur flying past Emon high above. Soon after, while the party was retreating from the green dragon, Raishan, Umbrasyl swooped down, following the party across the rooftops of the Cloudtop District.

"The Family Business" (1x47)

After the Chroma Conclave conquered Emon, Umbrasyl attacked Westruun and roosted at the peak of the enormous Gatshadow Mountain.[9]

"In the Belly of the Beast" (1x54)

Vox Machina managed to trap Umbrasyl in Percy's mechanism. With the help of the goliaths, the battle against the beast began as Vax and Scanlan teleported into the belly of the dragon, which after a few rounds fled toward its lair.

"Umbrasyl" (1x55)

As the battle against the dragon began again, this time within the beast's lair, Vox Machina and Shale managed to finally kill Umbrasyl, with Grog's Bloodaxe dealing the final blow.
