Seeing as the interiors were relatively settled, Jake decided to block as many enemy entryways as he could.
Jake ran around the perimeter soon seeing where the enemies were getting in. It was obviously in those areas without a sentry, and they simply made ladders. Or more accurately, climbable ladders, like those scaffoldings in construction sites.
However, it was obviously weak due to the rush, seeing as how it shook even if they were going in groups of ten or less. However, those who got in would wait along the interior side of the wall to form bigger groups before attacking.
By the size of those groups and their average levels, they'd definitely be wreaking havoc. By estimate, the average level was level 9 or even 10.
How could people around level 6 fight against them?
To be honest, if the Alterrans weren't here, he couldn't see how they'd win this war at all!
