Magic
There are limitations on certain types of magic in Zeitgeist.
Flight
Flight magic is rare. Magical flight is limited to a maximum of 5 minutes.
Teleportation
Gold blocks teleportation. A thin gold wire around a door or window blocks line-of-sight for short-range teleportation. A creature wearing a gold ring (or gold-plated handcuffs) cannot teleport.
Planar Travel
Although arcanists believe that it should be possible to use magic to travel to distant planets and alternate planes, no such trips ever last more than 5 minutes. It is possible (albeit difficult) to travel to the adjacent planes of the Dreaming or the Bleak Gate, but those who do so sometimes have trouble getting back.
Invisiblity
Magic that makes someone invisible for more than a few seconds is illegal in Risur, however this is a custom more honoured in the breach than the observance. The RHC and the military are exempt from this law, and potions of invisibility are widely available on the black market.
