Teleportation Circles

There are a few minor differences in regards to teleportation circles in Sitiath. First off, outside of houses of the Portal Guild, they are extremely rare. The rituals that make use of teleportation circles are also extremely rare outside of the hands of members of the Portal Guild. You can almost never buy them, and you will almost never find them as treasure. Members of the Portal Guild are forbidden to sell or teach others these rituals, and getting caught doing so usually means one's life, as well as the life of the one being taught.

The second major difference is that there are two kinds of teleportation circles. The first kind is one way teleportation circles, which work as described in the 4th ed DMG (pg 156). The second kind is linked teleportation circles. These also work as described in the DMG, but are slightly different as they are specially linked to another teleportation circle somewhere else. These linked circles have exactly the same sigils, except the last one is different. You activate a linked circle with a command word or command key, or sometimes both. The command key can be anything, from a special ring to an actual key. Normally, such keys must be inserted or placed in the proper place to activate the circle. Linked circles do not require the use of the Linked Portal ritual to activate as long as you wish to go to the linked circle, though you can use a linked teleportation circle with the Linked Portal ritual as normal.

Teleportation circles are very rare not only on the material plane, but also on other planes. They were only invented 50 years ago by the founder of the Portal Guild, and not many have been made on the other planes, though members of the Portal Guild have had a harder time keeping the secrets of teleportation circle creation from members of other planes, which means that it is slightly easier to come by the different portal rituals on planes other than the material plane. Most means of long range teleportation on other planes is done through teleporters, as described in the 4th ed DMG (pg 69). Most teleporters work without keys or command words, though they can be made to do so.
