Elaan

Blown by transdimensional winds through parallel planes, elaan are spectral seedlings. From afar they’re sometimes visible as drifting motes of pale light that catch on buildings, landscape features, and other creatures like ragged banners. Close up, elaan are revealed as eel-like creatures with disturbingly predatory heads. They cling to living targets, which might not even be aware that they’re carrying a phased, nearly invisible passenger. A clinging elaan eventually burrows into its target, where it lays eggs and attempts to influence its host to find a warm, dark, secret corner in which to curl up and wait for the eggs to hatch.
