Artanos got bored watching the demonic swarm going around in circles down below. With the orcs forcing the gates of the inner walls close, the demonic swarm had nowhere else to go. The bugs were not intelligent enough to make use of the stairs along the walls to go over it.
"Typical bugs," he muttered to himself then leaned against on the roof. He was waiting for the orcs to comeback and deal with the demonic spawns, since he was certain that they won't just leave them be.
Down below, the enormous Infested One finally exited the protection of the Sand Palace, and was now standing in front of it. It was busy giving out commands to its underlings.
The supposed defensive measures of the inner walls, the four magic towers, now became an additional passage for the demons to receive reinforcements.
