1) Portals:
Portals are created by Voage Runes. They are the most common means of transport in Downworld. The Voage Rune is very complicated and must be remembered perfectly by the person in order to create the portal. Portals are sometimes like moving strings, sometimes in the form of the whirl of a green colored liquid. The portal takes you to the place you think of while going through the portal. If usually appears in the ground.

2) Walk Through Veils
Walk through veils receive their names from that fact that they are simply walk through and are veiled, that is, hidden. They are similar to portals but are the rather Upperworldly form of portals. One of their sides is like a wardrobe and the other side is a mirror. If you walk through a wardrobe in Chicago you might end up coming out of a mirror in Arabia. The locations depends on what place of thing you think of while walking through. Usually there are vertical on walls, not of the ground like portals.

Time in Downworld
There are no clocks in Downworld. Therefore a way of measuring time was invented. Inspired from the Upperworld's clock, Downworldworlders invented the system of flower clock by enchanting a flower. The day begins with all the petals of the flower in the pot. When quarter an hour passes, quarter of the first petal attaches itself to the flower and the day passes like that. Night passes with all flowers falling, quarter of a petal every time.

Runes
Runes are special marks with functions. Each rune has its own capability. An invisibility rune will make oneself invisible. A torturing rune can torture someone. Some runes have different functions on different things. If an opening rune is carved on a wall, the wall will become walk-through. Anyone who touches the rune can then walk through the wall.
