Path of Evolution!
After losing almost half a million soldiers over seven days, the Council of Xylon was forced to change their tactic. They had been so busy with their internal strifes and establishing political connections with the Lords from other regions that they'd forgotten about the Trilance.
In their opinion, the Trilance was as good as destroyed and no more a headache for them. However, the arrival of no more than 100 people changed everything. The Trilance's reinforcement arrived.
At first, the reinforcement didn't seem like a big problem, but underestimating Michael and his subordinates was a grave mistake. Five armies had been bulldozed and only a few thousand soldiers of two more armies managed to retreat. Those who managed to survive weren't in good mental condition anymore, either.
On the other hand, the Trilance's reinforcement didn't even lose 10 members. None of the casualties was an Awakened either.
