Union is an artificially created demi-plane, designed to create new economic connections.
Six ic:Elven Trees stand in a hexagonal pattern at the centre of the plane, with pathways and aquaducts hung between their branches, allowing access to countless shops and taverns elevated in the branches. The central area between them is left open, allowing a direct view of the Grand Library on the ground below.
Around the six trees lie gigantic circular roadways which connect portals to different locations, traffic between planes avoiding the busy centre by moving around it all, each portal a small but strongly defended fortress on either side of the portal. From the roadways out, paths lead into the forest, eventually disappearing into the woods before reaching the edge of the plane.
