Core unit: the Goblin

Goblins are "degenerate" Orcs, who were originally "failures" in the Orc experiment, born from the blood of lesser demons (mostly Imps).
Goblins are small (between 4 and 5 foot tall), scraggy, physically weak, but very swift and agile.
The average Goblin is devious, cowardly, and stupid. They rarely attack unless having the numbers of a mob, preferring sneak attacks and (poorly constructed) booby traps.
In the Orc armies, Goblins serve as servants, scouts, skirmishers, and sometimes sacrifices for the Shamans, missiles for the Cyclops to hurl, or even food if rations become too low...
