It seemed the undead rats never dwindled in number but increased. The ruined houses seemed to get farther and farther apart leaving larger space to run. However the more space around the more undead rats seemed to be surrounding them. In a matter of minutes they had a group of twenty jumping at them from time to time.
Walker caught himself wondering why there weren't any other undead around until he started focusing on his surroundings. Every once in a while they would pass piles of old clothing or armors. Others there were piles of broken bones that looked gnawed on. These undead rats were consuming anything and everything that moved in their territory. This was their part of the ruins and nothing that entered left.
Immortal king was surely laughing at this, it knew the in and out of the ruins. Sending them to escape from this depth of the ruins was a death sentence!
