Here is Dhourn's exact location in Baldur's Gate 3:
(X: 121, Y: -242)
Dhourn can be found petrified near the Selunite Outpost in the Underdark. The easiest way to get to Dhourn is to travel to the Selunite Outpost Waypoint and then go through the broken window on the left side of the outpost. You will come across a few petrified drow, with Dhourn among them. Be prepared for a fight with a Spectator if you want to save Dhourn.
To start the fight, approach the petrified drow, and the Spectator will appear after a cutscene. During the fight with the Spectator, Dhourn will be unpetrified and will fight for the Spectator. You can turn Dhourn back to your side by doing any amount of damage to him to break the charm. Keeping Dhourn alive during the fight can be tricky since he does not have much health, but if you can manage to keep him alive, you can talk to him after defeating the Spectator.
After the Spectator fight, you will have a conversation with Dhourn, and he will reveal some information about the Adamantine Forge and show you a Memory Shard. Unfortunately, he and any remaining drow will become hostile towards you. However, Dhourn drops the Memory Shard, which is important in finding the Adamantine Forge, and the Icy Helve, which can be combined with the Icy Crystal and Icy Metal to create the Mourning Frost staff.
