Ferrystone

Description
Ferrystones are tools which can be used to transport the player and their party of pawns to either the primary portcrystal in Gran Soren, or any player-placed portcrystal in Gransys instantly. They are one-time use only so you will need as many Ferrystones as you need to teleport, make sure you have at least 2 or more on hand.

Also, if you have an "Escort Quest", you can use a Ferrystone to teleport yourself and the Escort to the location of a Portcrystal. They can be very useful when a Portcrystal is placed at the Quest Location at a previous point in time. Example; Escort the person to Greatwall, with a Portcrystal placed at the Greatwall, you can use a ferrystone to teleport yourself and the escort there, and finish the quest very quickly.

Locations

 * Ferrystones spawn in the center of the primary Portcrystal in Gran Soren outside the pawn guild, however the respawn rate is rather lengthy. Another place to find a ferrystone which spawns rather quickly, is on a small boat floating on the water next to a small pier, it is located directly behind the Bandit Fort that is near Witchwood Forest.
 * They are also available for purchase from Fournival for 10,000 gold or the Black Cat shop for 20,000 gold. Fournival only keeps 3 in stock at a time, though they will restock every day. Fournival will sell them for 9,000 gold each if you help find him innocent in the Main Quest Trials and Tribulations.
 * They can be found in chests, mostly in the Everfall but in other locations as well
 * Monsters in the Everfall occasionally drop them as loot, especially Grimgoblins.
