The Realmgates

Built during the Savage Age, the Realmgates have become the backbone of trade and travel between Realms. Each Realm has two Realmgates, one connecting to another in a different Realm. The metal’s color and writing characters tell a person where the Realmgate is located and the color of the vortex tells one which Realm is on the other side, if the single letter on top does not clue a person in for some odd reason. The blue Realmgates are Over-realm based ones with the green vortex set to the Mid-realm and the red one set to the Under-realm. The green Realmgates are Mid-realm based ones with the blue vortex set to the Over-realm and the red one set to the Under-realm. Last, but not least, the red Realmgates are Under-realm based ones with the blue vortex set to the Over-realm and the green one sed to the Mid-realm. If anything were to happen to them, like, say, some mad scientist blows them up, trade would be stop and travel would grind to a halt, so defending the Realmgates is very important to Realmfleet.
