Troll Update.

Trolls are horrid carnivores found in all climes, from arctic wastelands to tropical jungles. Most creatures avoid these beasts who know no fear and attack unceasingly when hungry.
Trolls have ravenous appetites, devouring everything from grubs to bears to humanoids. They often lair near settlements and hunt the inhabitants until they devour every last one.
Trolls walk upright but hunched forward with sagging shoulders. Their gait is uneven and when they run, their arms dangle and drag along the ground. For all these seeming awkwardness, Trolls are very agile.
A troll's rubbery hide is moss green, mottled green and gray or putrid gray.
