Mordenkainen's Tome of Foes

GE RYON

Geryon is locked in an endless struggle with Levistus

for control of Stygia. The two have fought each other

for centuries, each displacing the other innumerable

times. Currently, Geryon occupies an odd position in the

infernal hierarchy. Although Levistus still claims lord-

ship over Stygia, he has been trapped in an enormous

block of ice at the command of Asmodeus. For his part,

Geryon marshals his followers and seeks to discover the

means to replace his hated rival.

Among the archdevils, Geryon and Zariel are espe-

cially known for martial prowess. He is a ferocious

hunter and a relentless tracker. Other devils command

legions and bid their followers to battle their enemies.

Geryon loves the feeling of flesh and steel being sun-

dered beneath his claws, and the taste of his foes' blood.

His ferocity serves him well in Stygia's frozen waste,

but it has also limited his ability to collect souls and

forge an effective hierarchy. Sages who study the Nine

Hells believe that the battle for control of Stygia is a

test staged by Asmodeus in hopes of purging the worst

impulses from both Geryon and Levistus, or at the very

least opening the door for a competent replacement for

both to rise from the ranks.

CHAPTER 6 I BESTIARY

GERYON'S LAIR

Geryon has recently reclaimed his ancient fortress,

Coldsteel, a sprawling complex that rises from the

ice and snow at the center of Stygia. He roams the

passages of this place, scattering the ice devils and

minotaur slaves he took from Baphomet, raging against

Asmodeus's betrayal while spitting oaths of vengeance

and hatching mad schemes to reclaim his standing

from Levistus.

Lair Actions. On initiative count 20 (losing initia-

tive ties), Geryon can take a lair action to cause one of

the following effects; he can't use the same effect two

rounds in a row:

• Geryon causes a blast of cold to burst from the ground

at a point he can see within 120 feet of him. The cold

fills a cube, 10 feet on each side, centered on that

point. Each creature in that area must succeed on

a DC 21 Constitution saving throw or take 28 (8d6)

cold damage.

• Geryon targets one creature he can see within 60 feet

of him. The target must succeed on a DC 21 Wisdom

saving throw or become restrained for 1 minute. The

target can end the effect on itself if it deals any dam-

age to one or more of its allies.

• Geryon casts the banishment spell.
