Planar Travel

Planar Travel is the process by which creatures and objects from one Plane to another.

Portals

Via Tears

Planar tears are rips in the fabric of the Planar Mesh, allowing direct contact between 2 planes. These form naturally when large amounts of planar essence of a plane is gathered in one location on another. A common example of this is that of volcanoes; many large volcanoes have tears to the Plane of Magma or the Plane of Fire at their hearts. These are very stable, but very difficult to control; tears are essentially open doors between the planes and anything may pass through them. Crimps are another form of naturally occurring tear, leading specifically to the Fey Sphere

Via Breaches

Planar breaches are similar to tears in some aspects, but are much shorter lived. Powerful magic can create a breach which tends to stay open for only a few hours. Unlike tears, they can be manipulated to close early or change in size with the proper knowledge.

Via Gates

Planar gates are artificially created tears. They require near constant magical energy to maintain, but can have a large level of control exerted over them. Depending on their construction, gates can be one way or exclude travel to creatures with certain aspects.

Teleportation

Teleportation Spells

There are a variety of teleportation methods available. These differ from the aforementioned portals in that they do not "open", rather it is an instantaneous transfer of material. This offers advantages and disadvantages; on the positive side, travel in this way means that there is no chance of unwanted visitors traveling through in the opposite direction. On the negative side, single use teleportation can be rather expensive.

Teleportation Circles

This can be somewhat mitigated with the construction of a permanent Teleportation Circle, though this also somewhat counteracts the privacy of a single use spell in that it provides a stable anchor for others to teleport to. Part of the ritual in construction a permanent circle is inscribing a unique code into the Akashic Record. If the chosen code has already been used, then the ritual to create the circle will fail.
