Sink Worm

The ground bucks and heaves as a vast pale worm bursts from beneath the sand, cavernous jaws agape.

Combat
A sink worm travels underneath the silt and sand, moving silently until it bursts out, surprising its victim and usually swallowing it whole. If a sink worm is pursuing a target that is fleeing, it will often use its phasing ability to rush ahead of its prey and then burst up from the sand in front of them. If sorely injured, a sink worm will seek to flee beneath the sand using its phase ability.

Description
A sink worm is huge white worm that travels beneath silt and sand, leaving a scarcely noticeable trail. In spite of this clear warning sign, few prey escape once a sink worm begins hunting them.

Sink worms are solitary, meeting with others of their species to mate only once every three years. The hatchlings are left to fend for themselves, and most turn cannibal immediately, with the strongest few surviving to burrow away. Sink worms will try to eat nearly anything and need at least one man-sized victim per day.

The sink worm sucks sand and silt through its body, filtering minute particles of air past gills which allow the creature to breath under the silt or sand. It is this removal of air which causes the characteristic sunken depression in the surface of the sand or silt through which the sink worm passes.

Sinkworm "gills" are a curiosity among sages, so a sinkworm egg would be worth whatever the owner asked for it. However, the difficulty in locating the eggs makes this nearly impossible. Sink worms can stretch up to 32 feet long or more. A sink worm is pale white in color, resembling a huge maggot.
