Zandalar Isle is ruled by King Rastakhan – a jungle troll witch doctor and keeper of troll lore. This island is the home of the Zandalar Trolls who gave us quests for Zul’Gurub to oversee the destruction of Hakkar the Soulflayer. Its capital city is Zuldazar.

To the southwest is Isle of Kezan.  To the north is the Broken Isles, and Westfall to the northeast.

Many huts, totems and ziggurats may be found scattered throughout the isle.  Zuldazar is the biggest troll structure in the world of Azeroth.  Zul’drak pales in comparison.  Prospector Brann Bronzebeard traveled here by Gryphon after his trip to Isle of Kezan. He confused a structure of a series of Ziggurats with a high mountain. A city carved out of stepped pyramids and tiered walls.

All troll tribes around the world of Azeroth send emissaries to Zandalar every six years, a tradition which purpose is to discuss matters that affect all trolls.

Religion
This is what is read on the tablet at the Altar of Zanza in Yojamba Isle, Stranglethorn Vale:

We call upon you, Zanza of Zuldazar.

Bless those that ask for your help.  Loa Zanza, Bless those that would ally with the Zandalarian people.

Aid us in this time of need.  Aid us Loa.  Give us the power to strike down our enemies.  Give us the power to once more defat the Blood god.
