Before the fall of the Empire in 883 GUE, the Tunnels of Love were a favorite of the Kingdom's honeymooners, located a stone’s throw from Aragain Falls. The Tunnels were well-known for their vast honeycomb of passageways, and couples had been known to raise entire families just trying to find their rooms. In 873 GUE, rates ranged from Zm2 for a room to Zm10 for a Honeymoon Suite.
