I've mentioned these ideas in the past, but I'll bring them up again:
- Auction House NPCs in Mhaura and Selbina
- Home Points in Tavnazian Safehold by Sealion's Den, Auction House, and maybe also in the upper section where Justinius and other NPCs reside
- Home Points by the Trail Markings in Beaucedine Glacier and Xarcabard
- A means to check the amount of Alexandrite given to Paparoon as part of the quest "Duties, Tasks, and Deeds"
