Engak

A worm that's as large as a train found all around the world. Various types exist, such as Desert Engak and Mountain Engak. These names roughly translate to "Desert Devourer" and "Mountain Devourer". Though well known in Seloren, they are not found in it, or have an official name in the ancient language.

Appearance
Engak all have the same color and basic appearance, being that of a large, spiked worm around the size of an average train, though the size varies from specific species and age. The older it is, the larger it is. In turn, Desert Engak tend to be large, due to the usually larger amount of space to grow in. Being that they are very similar, the biggest difference, other than their size, is the hardness of their 'teeth' and strength of their maws. Respectively, a Mountain Engak has stronger maw, and harder teeth.

Trivia

 * Orignally intended to be found behind The Mind's Door.
 * While it was originally inspired by the worms found in Middle-Earth, it is also inspired by the ones in the Diablo franchise (Specifically Diablo III).
