Ciceros Strait, well-known for its dangerous whirlpools and shark-infested shipwrecks, is located around the islands of the Cyclades in Endless Ocean: Blue World. It is believed to be the resting place of Valka Castle. L&L (R&R) Diving Service proved this theory correct. It is also where Triton Village sank into the sea, and where the man-eating monster Thanatos lurks.
