While the vanguard was being got in a trap in the depths of the complex, the rearguard of Freygar's group was passing through hard times as well.
The initial plan was to make them split into smaller groups and give chase to the prisoners that would probably be spread through the complex and running. Differently from the vanguard, they had not a leader or someone to coordinate them in each group. It was an action that depended on the competence of each member individually.
Of course, work like that was bold and even risky to some extent, but not when your enemies were apparently so weak and unorganized, and even more knowing that the inmates would do the same thing among themselves, even though they had less power than the Ridires.
