From the Introduction to the PDF:
"Orcs By The Horde
Of all the enemies player characters love to engage in lethal combat in fantasy games, no more popular enemy exists than orcs. A default enemy, more an excuse to have the characters make use of their combat moves, orcs are a staple monster in many tabletop fantasy roleplaying games.
Modern MMORPGs such as World of Warcraft have begun to challenge this attitude, making orcs over as the honourable Klingons of fantasy roleplaying games; but the Monsters of Legend and Cities of Legend-Skarr: City of Orcs source books still cast them in the same light as the old RuneQuest game – as monsters.
All that changes here."
