Xundi

 Shi is a marid who was freed from the control of Algar Dyomin by Mighty Nein. As an NPC, is played by Matthew Mercer.

Appearance
Xundi is an impressively large, aquatic humanoid, standing at full stance around 7-8' tall. His face is fish-like, with a wide mouth and small fins that crest his head. He has blue-green skin that glows faintly, and his chest and torso are rather rotund. He wears a small vest, and has long, thin arms that end in somewhat webbed, clawed fingers. The lower half of his body is comprised of constantly rushing, swirling water.

When the Mighty Nein first encountered him, he was forced to wear a thick metal band around his neck indicating his captivity under control of Algar Dyomin.

Personality
Under the control of Algar, Xundi displayed general irreverence towards his master. He spoke with undertones of "exasperation and eye-rolling." He also seemed mostly unbothered by the appearance of the Mighty Nein in the Sluice Weave, whereas Algar was quite alarmed that any intruders could make it to there.

Xundi properly introduced himself to the Mighty Nein as "Khedive Xundi". He mentioned to the Mighty Nein that they could find him in his home: the "Silver Silt Palace" in the "endless oceans".

Quotations
"Khedive Xundi is my title. I've been held here for too long. Should you find yourself among the endless seas of my world, come to my Silver Silt Palace." – Xundi to Fjord after the Mighty Nein released him.

Trivia

 * Presumably the Silver Silt Palace is located in the Elemental Plane of Water.
