Portquartz is an arcane, colourless gem found in the caves of Winterfrost, having limited capabilities to teleport an individual.

With some basic blacksmithing and magic refinement, it can be turned into a Wandertail, which allows for teleportation, free travel and rentry into Wanderveil.

Portquartz, unlike most gems, can be melted without destroying its structure, which can be used to repair Wandertails. This molten liquid Portquartz is known as Portquartz Amber due to the heating process making it appear like malleable amber.
