Kidnap a Lord
While the interior was under control, the outside wasn't too far from getting settled either.
Although Epo mobilized their thousands of troops, civilians, and slaves, level 5 walls and dense sentries weren't something they could easily take.
More and more of their troops fell, but they continued on, trying to get more people inside by ladder or going over each other.
However, because the chaos in the interior had begun to settle down, more of the guards and Alterra's had become available to go around the battlements, preventing trespassers from getting in.
What's more: There were certain people beyond the level cap waiting somewhere, waiting for their timing, to finish this as quickly as they could.
It had to be said that a smart territory, unless they were really really certain about the strength of the enemies and their capabilities, wouldn't attack another territory head on.
