At night, the waters beneath the surface around Marrow Isle are still. Almost too still. The Leviathan Eels return to their caves and the fish have mostly retreated to their own dens. A few bioluminescent jellyfish can sometimes be seen drifting through the waters.

However, cutting through the darkened sea water, a strange clicking can be heard. It grows ever closer, from the moment the sun goes down for as long as you are underwater. It's best to hurry back to land, before your Constant Companion/a> arrives. [Content warning: realistic spider/bug]
