Gold and Teleportation

In Zeitgeist, in addition to its value as a precious metal for jewelry and currency, gold can be fashioned into a barrier against teleportation. While characters can teleport freely while carrying gold, but they cannot teleport through an opening framed in gold. Certain buildings thus often have thin strips of gold inlaid around doors and windows; typically, this gold is concealed by additional masonry or some other artistry. Prison cells meant to hold eladrin and others thought to be capable of teleportation are often surrounded by rings of gold.
Similarly, a creature wearing a gold ring — or bracelet, or even a thin thread of gold wire — cannot teleport or be teleported, so those wary of abduction might wear hidden gold toe rings to stymie wouldbe kidnappers. Simply carrying or wearing gold is not a problem unless it forms a full loop. Even with full circles of gold, the protection can be bypassed by simply removing part of the ring. This, combined with the temptation for thieves, keeps gold warding circles from being in common use.
