Portcrystal

Portcrystals are an item used to add a location you can teleport to via a ferrystone. Portcrystals can be picked up and set down whenever one wishes to relocate it.

The Arisen can find their first portcrystal at the end of the Griffin's Bane quest. In the room for your final encounter with the Griffin of this quest, there will be a shining blue crystal on the othr side, this is a portcrystal. It is ill-advised to have the scrivener at the Black Cat duplicate it as it will not function properly and could only be used as some sort of bad joke as a gift to somebody's pawn, thereby wasting 300,000 gold making an item that won't function.
