Melinda had asked him to go there and fight in the northwest region, as it was the most damaged one. Arthur did not want to let her down, but what could he do?
The visions showed people he cared about, and that was only one part of it. That strange monster horde has something to do with the place Arthur saw in the memories, so if he went there, he could not only save his friends but perhaps end the beast's invasion.
But how would he leave? Everyone was counting on him, and who knows what may happen while he was away.
"The people I truly care about are safe in the capital and near Frostpeak. Even if this place falls, not that much of a deal." Arthur thought.
Louis was the only person Arthur had a somewhat connection while he was there, but that was it.
With those thoughts in mind, Arthur destroy the corpse of the giant, and then he left Markhar city, straight towards Embercoast to speak with Melinda again.
