===Nature and Behavior of Fell===
Deceased that have recently become Fell are ungral, a High Elven word meaning “tethered dead.” Ungral often appear almost indistinguishable from living creatures, though a violent or debilitating death will typically leave obvious signs. Ungral retain the intelligence they had in life, and not all of them have yet succumbed to evil. 

If an ungral fails to feed, it becomes a faengral. 

A faengral that fails to feed becomes a maelgral, or “walking dead.” 

Finally, as the bodies of the Fell inevitably continue to rot and decay, they eventually become indistinguishable from animated skeletons created through necromancy. When they reach this stage, they are no longer considered Fell. 

Ungral, the first stage of unlife for most risen, are typically intelligent enough to hunt on their own, stalking their prey on the edges of civilization, sneaking into and raiding outlying farms or hamlets in the dark of night. Many of these cunning creatures have even learned to hide beneath the surface of swamps, lakes, and other bodies of water during the day. At night, they crawl out of the depths and sneak into river towns and coastal cities to hunt. On the Sea of Pelluria, amphibious dead have become such a problem that most coastal settlements are forced to maintain boat patrols along their nighttime shores.

Faengral and Maelgral, as their minds drop to the level of animals, often turn to hunting in savage, roving packs, where their decaying minds and limited ability are made up for by numbers. Hiding in woods, ruins, or empty caves during the day, these packs shamble deliberately into villages and outposts as darkness falls, attacking without warning. These nightmare bands have forced many human settlements to build high walls and lock their gates when night comes. When they attack, the faengral and maelgral bring down their prey by swarming them, and in their frantic compulsion to feed, they often end up in savage fights among themselves.

The Fell are creatures of darkness, preferring to hide in dim and secret places during the day, avoiding the sun whenever they can, biding their time before stalking into the night to hunt. Though light does not physically harm the Fell, they seem almost afraid of it and it clearly affects their ability to see. Undead will often shy away or even flee from sunlight, and even bright torchlight and lamplight seems to affect them.

The maelgral, or “walking dead,” is the last state of the Fell before total decay. Maelgral have lost nearly all of their personality and are less dangerous, though more durable, than the other forms of undead. They have more durability and an inability to feel pain, but no longer have the ability to claw or bite their prey; instead they can only attempt to bludgeon their victims with desperate clubbing motions of their often handless arms. Unlike a lesser undead (skeletons, ghouls, ghosts or zombies), a maelgral retains some element of animal cunning.
