Aetheria City, or Lorica, otherwise called The Capital, is the head of the Aetherian Kingdom, a center of crafting, and home to many guilds such as the Knights of Aetheria. It is also home to the king of the continent King Runehammer the II.
It also houses the Greater Aetherian Academy, a school for Ardenvell's most skilled inhabitants.
Many Terrarians live within the walls. They are helpless and beg the NPCs for food and emeralds. The Legion sympathizes with them and tries to help them the best they can.
It lies along a central spot on Ardenvell's western side, directly west of Ravensong Forest, and northeast of Voidmantle Wood.
