What to do
Prospector Loren at the Archivum in Ulduar wants you to locate the entrance to the Celestial Planetarium.
The quest giver's words
Listen, <lad/lass>! Azeroth's fate is at stake here.
Our only chance is to get to the Celestial Planetarium in time to find this Algalon and stop him from beaming back any messages to his Titan masters.
Locate the Celestial Planetarium and come back with any information you get. We might still have some time to prepare for Algalon's arrival.
Progress
Did you find it, <name>?
Completion
It's locked? Figures!
I'll let Brann know... maybe he can uncover something in the Archivum.
Category: Ulduar (Raid).

What players recorded
Everything below this line is a different kind of knowledge from everything above it. Above: what the quest is, the same on every realm. Below: what actually happened when people played it, uploaded by them, with the number of runs printed against every figure. It is an observation, not a fact about the quest.
Nobody has completed this quest with telemetry on yet, so there is no timing. Everything below is drawn straight from the 0 recorded attempts the hub has.
How precise this guide is
Early guide Built from 0 runs by 0 players – low confidence. Every upload of this quest sharpens it: the hotspots tighten, the order and the timings settle, and the parts below unlock as the sample grows.
- Where to go – pick-up, objectives and hand-in needs one recorded run not yet
- Typical time and objective order – median and middle half needs 3 completed runs (now 0) not yet
- Tips – what most players do needs 5 runs (now 0) not yet
- Where players die – death hotspots on the map needs 5 characters from at least 2 different people (now 0 from 0) not yet

The route
An early route: drawn from the first runs and sharper with every upload. Pick-up, hand-in and the objective hotspots are where the quest is, so they are shown from the first run.
Map coordinates are the addon's own 0–1 zone coordinates (Ulduar), origin top-left, x to the right and y downward. Drag the zone map to pan, ctrl/⌘ + scroll or the buttons to zoom; the grid lines are tenths of the zone.
- Pick up
