It was quick and simple.
After arriving back in Ooze Town, Alaric immediately ordered Clarus to initiate a set of plans to take over the Great Forest of Neuling. With both White Bridge and Grander out of the way, this entire territory was now his.
Clarus convened with Mike, who brought his forces to the closest village, Angerfall Village. It was the most militaristic village in the vicinity of the Great Forest of Neuling, so Alaric allowed Mike to bring Sonic with him. A rank-3 force would probably be necessary.
'Clarus has already set out with Gunnar and the giant slimes to annex both Eden and Fen Village. Both villages are especially loyal to the Neuling Kingdom, so I instructed him to kill their leaders and instill propaganda into the people with his ability.'
Bonnie is also following Clarus, as she wanted to see what a battle was like. Alaric allowed her to, simply because it was less of a battle and more of a massacre.
