The Tavern Trials - Gold Hoarders

Sounds cool!

@havicgaming2244 A neat idea though I feel this one needs more thought as it feels very similar to existing quests for the Gold Hoarders, I know you wish to incorporate the idea of a new tavern or Fort Merrick's Tavern however I would simply change one of each existing taverns in each region to become the central hub for each faction;
The George and Kraken at Sanctuary for the Merchant Alliance
Drowned Rat at Plunder for Gold Hoarders
Broken Tusk at Galleons Grave for Order of Souls
The factions could be switched around, I just feel those regions represent those companies best, however I wouldn't change the outposts for others as this give the most spread out coverage of the entire map

As for the quest itself, for a lvl 100 Gold hoarder you have made that faction lots of money over your time and thus should be entrusted enough for this new quest

Vault Deposits
Instead of stealing loot from the Vaults of the Ancients, the Gold Hoarder's decide to store valuable items inside them, as such you are given the option to purchase locked chests much like the commodities feature for the merchants but without the "sought after/surplus" feature. Players must then take this valuable loot over to a certain islands (perhaps they use the ancient vaults or make their very own at other islands such as thieves haven)

Another option would be to incorporate the burying treasure feature and then selling the map to the GH for a tidy profit however I believe the quest board/bury feature needs a complete rework to be worth doing.
