To be able to meet Lothren and use his services you must complete a quest:
|Note: Listed in Adventure Log as Great Warrior Spirit|
Before this event takes place, he's just an elusive encounter you can't complete around Penekarn Lane.
After this quest, he becomes your mentor on the way of Palk, the Great Warrior Spirit.
Lothren will also perform the following services:
- Unknown item identification (free, but AG only).
- Removing Icons from imbuable items (Cost: 64 XP per imbuable item freed).
These services will only be shown if you need them, so, e.g. if you don't have any Unidentified Items on you the option to identify them won't be available.
