Uldir Guide

30-second TL;DR

Adventure Guide says

Millennia ago, seeking to understand the nature of their eternal foe, the titans constructed this sprawling underground facility to research and quarantine captured specimens.
They hoped that by studying the void energy that bound the Old Gods, probing it for weaknesses and reactions, they could find some way to neutralize it.
The Adventure Guide lists 8 encounters: Fetid Devourer, G'huun, Vectis, MOTHER, Taloc, Zek'voz, Herald of N'Zoth, Mythrax the Unraveler, Zul, Reborn.
