The Island Of Lemoy is one of many islands situated off America's west coast. Situated not very far from the ocean door that Stingray exits from, it is home to Titan's surface agent X-20. It makes a ideal base of operations, as it is relatively close to Marineville and X-20 can monitor the comings and goings of Stingray.
The only dwelling on Lemoy is X-20's house, originally built in the 1930s by an eccentric millionare. The house sat abandoned for many years and fell into some disrepair, but stood up relatively well to the bad weather that plagues the area. Despite the uninviting façade, the interior houses superior technology graciously provided by King Titan, hidden away behind everyday objects such as paintings and a table.
