As the hermits say, ruirri is the spider-like creature which lives in the mountains. Many people say that ruirri are one of the products of Gmurrian magicians who wanted to make the perfect bodyguards to protect their people from human expansion. Made from the alive invertebrate organism with mechanic inserts, strengthened by the magic powers, they present the real danger. I came to an opinion that ruirri had left their masters and began to advance by themselves. I had a look at the body of dead ruirri. Its bones really look like some kind of steel skeleton. I haven't found any stomach, so it is still unknown what do they eat; but, it can be said with certainty that they haven't forgot their function - they attack anyone who comes close to the mountains. On the other hand, ruirri are very rare, and I doubt whether you'll meet them at your way.
