The quest Lost Souls is part of the Codex challenges in the Shattered Temple region Throne and Liberty. It will have players helping a Purelight Wizard put some poor souls to rest, and while the process itself is pretty simple, actually doing them can be a bit confusing.
This mission involves freeing the spirits in question. Getting to the places you need to go is probably the hardest part of Lost Souls, but unlike Throne and Liberty's The Treasure of Daybreak quest, this one doesn't require any fancy steps and is pretty easy to complete once you know what to do.

Throne and Liberty Lost Souls Walkthrough
To start this quest, go to the Light Sanctum Ruins in the Shattered Temple region. There is a wizard outside the temple watching over some undead in the pit below. Talk to him and he will ask you for help in resting the poor lost souls. Very little combat is involved here, but as always, upgrade your equipment Throne and Liberty if you have a hard time surviving. The mission steps here are:
- Talk to the guide.
- Interact with the wandering spirits below.
- Interact with the Soul Magic Orb in the destroyed tower next to the waypoint.
- While burning from the Soul Magic Orb, quench yourself in the waterfall near the tower.
- Talk to the guide again.
How to reach the Soul Magic Orb
The first two parts are self-explanatory. Talk to the wizard and touch the ghost orb at the bottom of the pit. After this you need to reach the interior of the ruined tower past teleport to the waypoint and climb the tree branches. Reach the highest branch like the picture above and jump to open window.
Then press the Soul Magic Orb, and a blue flame will cover your body. When you start burning, use your Glide Morph to reach the nearby waterfall. It should be slightly to the right of the window next to the Soul Magic Orb. Just touch the water to extinguish the flames and scratch the objective off your list.
From here, all that remains is to talk to the guide again. He will thank you for your work and reward you with a handful of money and materials. This includes some Precious Armor Growthstones and a Noble polished crystal. The former is for upgrading purple-tier equipmentwhile the latter is for make more precious growth stones and other materials.
