Tiger Widow Island is a small tropical landmass in the Endless Sea. It is named for its most infamous inhabitant, the massive Tiger Widow spider. The Tiger Widow makes its nest here, but it is not the only resident. The island is also home to sand worms, which burrow beneath the surface and react aggressively to any movement above. The location of Tiger Widow Island is not listed on any published map or included in any map database. The only map to reveal its whereabouts was a chart prepared by Captain Soto and hidden in a lantern on board Misfortune’s Keep.
