Lord of the Rings - Fellowship of the Ring.
Oh sorry, sorry...you meant here. My bad.
Actually, The Hobbit is the first piece in which they appear. Tolkien even left a footnote there explaining that these creatures are not related to orc- prefix used with whales.
Orcs will be produced primarily in your Armories, so make sure you upgrade those.Okay .......... I'm on level eight, Portal is built...........producing mushrooms........... WHEN will I start to produce "Debris" and Orcs ??
(Try to stay focused, y'all !)
