Editing Grell (section)

==The Basics==
Grells are ambush predators mainly found in ruins and the [[Underdark]].  They look like floating brains with spiky jellyfish tentacles and bird beaks.  They are immune to electric attacks and can paralyze prey with their tentacles.  Because they don't have eyes they perceive the environment with their sharp hearing and a shark-like electroreception sense.  Their electroreception sense allows them to communicate with each other completely silently through electrical impulses.

The second edition Monstrous Manual introduced that grell live in a hivelike colony. They are egg-layers. The alpha of the colony is "patriarch"; betas are "philosophers" with the rest warriors. Patriarchs are immotile masses of tissue; but if encased in an airship, they can take to the skies or even deep space beyond. They answer to an "Imperator" of all grell. They have no place in an ecology beyond Apex Predator; if they show up, expect the death of all rival sentients until they get bored of the hunt and move off.

Warriors can use grell-specific weapons, like the Lightning Lance. The language is a mixture of chirps, tentacle-movement, and psi. Non-grell lifeforms are only prey, or inedibles, or predators to them. 

Despite that grell society is A Thing, those grell which most adventurers encounter are, still, feral grell who choose to live like animals, either solitary or in small packs.
