Aleya

The Sundarbans mangrove delta — vast, labyrinthine, and treacherous — has always swallowed fishermen. The Aleya are their ghosts: men who drowned in unmarked channels, unable to find their way home, condemned to wander as wandering lights above the water.

In Bengali belief, the Aleya retains the fisherman's confusion and desperation. It seeks to guide others — but guides them wrong, leading them into the deep channels where it itself drowned. It is not malicious: it is simply lost, and does not know it.

The Aleya appears as a pale or bluish-white flame hovering one to three feet above swamp water. It bobs and shifts with an almost purposeful motion. Sometimes multiple lights appear together, moving in loose convoy.

Rational explanations — bioluminescent bacteria, methane combustion from decaying matter — have been proposed by scientists, but cannot account for the lights' apparent responsiveness to observers.

The Aleya's power is disorientation. Fishermen who follow the lights report losing all sense of direction, even in waterways they have navigated for decades. The lights move just fast enough to keep a follower engaged but never close enough to reach.

Some accounts credit the Aleya with causing compasses to spin and lanterns to gutter when approached.
