There are many portals in Rainbow Skies.

Each portal is connected to several other portals. Think of it as a railway system, where each station is connected to other stations, but you cannot travel directly from one station to every other station.

To unlock a new portal that you have discovered, you must obtain its portal crystal. Portal crystals can be found, obtained as quest rewards or bought in shops.

Using a portal requires a small fee. You can use portals as often as you like.
