Many phrases in the local vernacular refer to Lake Rumare, such as "throwing money into Lake Rumare" to save time instead of "visiting that dump (the Imperial City)".
The main bridge across the lake is called the Talos Bridge and is located on the west side, between Weye and the Chestnut Handy Stables. Another wooden bridge (not marked on your map) is to the north, fording Fort Empire and Fort Caractacus. An island on the southern part of the lake houses Fatback Cave. The Ayleid ruin Vanua can be found southeast underwater, before the lake opens into the Upper Niben.

- One unusual island is located in the southeast part of the lake. If you swim out to this island, you discover that its banks are too steep to climb. Even if you reach the tops of the banks, there is an invisible wall that prevents you from entering the island. This island is the destination of A Mage's Staff, at which point you can access it through Wellspring Cave.
