The Gren are a race of militaristic humanoids that have overcome their natural weaknesses to become some of the most feared warriors of the 13th Age.
The fleshy beaks, frail-looking bodies, and loads of steel contraptions are the hallmark of the Gren. They alone have mastered the art of invention, and counter magic with science. They tend to be wily and clever, and excel at creating contracts that bind the signer to unscrupulous deals. But they will never betray confidence, for they know that to do so would ruin their reputation as Orcs—honorable fighters.
