While not directly linked to a species or group, its vital for travel and shipping. There's five types of gates. Ones that link worlds by a gradual travel may allow a glimpse at Limbo. Limbo is the gap between worlds. It's usually described to have a chalky feel with very little light. Despite this, it's very easy to see around the area.

Holes only go one direction. They swap between directions, so it's just a matter of time. The gate itself looks like an extremely deep hole. Using the gate gives off the feeling of falling as well. These link the two world. This type of gate is always natural occurring.

Doorways are an instantaneous portal. They can link the two worlds or are used to get to a different location. It can be linked to a key or a door. These gates are made artificially through magic.

While like Doorways, Tunnels are more gradual. You can go back and forth just by walking a short distance. The landscape changes by approximately. These can be natural or artificial.

Rifts are small, naturally occurring gaps between areas. These need to be temporarily amplified by magic in order to use it for travel. These are fairly commonly with large distances, so flight and ships are used less compared to the alternate realm. Trains taking advantage of these are used for traveling and the shipping of larger objects.

Average Portals are made through magic circles, but there is another variant. These are used for shipping. A method for smaller objects is transport seals, two or more circles that only travel between each other. It's recommended not to use it to transport multiple people at a time. It may lead to a few people being swapped or fused.

The other variant is described as a black hole with tendrils. This is thought to be used to restrain targets. These can only be used by powerful deities. It is capable of transporting multiple people without any known problems. It's unknown where it leads, but the common consensus is that it leads to the Underworld
