Orcs

Orcs are dull-witted cave-dwelling scum found only in the magical realm of Middle-Earth. The Orcs work for Sauron - no-one knows why, they only know that they are willing to die in huge masses to acheive nothing in particular. Orcs are a unique race in that their defence systems are not great. The tiniest poke will kill an orc. Thats right, so an arrow in the finger will immidietly kill and orc, and then even something as stupid as a whack on the head with some staff will kill an orc. They really are very weak, weaker than Grunts, weaker than Sentinels, and even weaker that the hapless Stormtroopers.

The Orcs are one of the races that rebel against the League, so the League declared war on them. The League has no power over the magical realm of Middle-Earth, and getting there isn't easy, so no battles have taken place in this war yet.
