This is to change the mechanics for how the locations on the navigator work.
Using the existing Guild Augment Slot Mechanic
Navigator has X number of slots (6 tier 1, 9 tier 2, 12 tier 3).
You buy augment crystals from the Navigator Vendor in House K who has a teleport to any area. You slot these into the Navigator where they last for 1 week.
So for example, the list of Crystals would include:
3 Barrell Cove - Salty Wench Tavern
Sorrowdusk - Eye of Kol Korran
Necropolis - Orchard Entrance
Necropolis - Bar
Meridia
Crafting Hall
Reaver's Refuge - Bar
etc (until you list all public places)
You could then slot the places you want for the navigator instead of having fixed locations that no one uses.
Advanced - Tier 3 Only
Add places like Chains of Flames that can be slotted
