The Battles of the Outer Wall (Part 1)

At this time, the outer walls were no less chaotic than the interior. Maybe even more so because there were a lot more people there. 

The majority of both forces were in this area added to the chaos created by the citizens themselves. 

There were still three large teams outside, who were blocked in time before they could follow Althea's footsteps of smooth sailing to the inner walls. 

If even a portion of these teams passed through, then Altera would've won this war. However, no one was complacent. They headed to the walls with the attitude that the other two teams were blocked. 

Two of these teams were already by the walls, just waiting to get past.

Drake, Henry, and the others were also there. When the Alterans started causing chaos in the inner walls, almost all of the guards were summoned in that area, leaving a lot of openings for them to sneak out of.
