After giving Matthew the confirmation, Trolgar quickly led the group outside once again as he needed to inform the trolls that they would be going out for war soon and there were still some things that needed to be done back in their base after the intense fight with the humans.
And just like what Matthew had said, they will be attacking the human's outpost together with the other ogres, so they also needed to inform the ogres about the golden opportunity for them to strike back and destroy one of the humans' outposts to suppress the humans' movements inside the forest.
So to do that, Matthew initially had planned to activate the yellow aura and run back to the first ogre village in half the time that they took to get to the troll village, but after talking about it with the group, they decided that Matthew should stay with the trolls for now to further cement their alliance with the trolls.
