Thoonum

Thoonum is a storm giant in service to Uk'otoa. As an NPC, Thoonum is played by Matthew Mercer.

Description
Thoonum is a huge storm giant with teal skin, glowing white eyes without pupils, and with ragged white hair and a beard that is tangled with kelp and various ocean detritus. Its head is nearly 10 feet wide. It wears a breastplate covered in seaweed and in runic symbols.

Personality
Thoonum is a servant of Uk'otoa and seems to take delight in destroying the Nein Heroez.

The Mighty Nein Reunited
Thoonum, joined by a number of deep scions, attacked the Nein Heroez. Its approach was signaled by an oncoming storm. The scions told Fjord that he must do as Thoonum commanded, or else lose all that he loved. Its attacks knocked Jester unconscious, at which point Fjord healed her and gave over the Cloven Crystal. Thoonum then went under the ship and destroyed it from below.

Jester Scried on one of the scions when the Mighty Nein were figuring out their plan, and saw that Thoonum and the scions were walking through the Menagerie Coast but had at that time not yet reached the temple in the Cyrios End Forest. Later, as the Mighty Nein were positioning themselves in the temple and preparing an ambush, Thoonum appeared. He stomped on the temple, partially collapsing it. The Mighty Nein quickly killed him, with Veth getting the HDYWTDT.
