I'm still also wondering what happened with Halsin and Aridan and the adventurers for the entire month since they left the Grove before the game begins. That is probably one of the biggest story issues I'm dealing with. Even if we assume the Grove is like a week's journey from the Temple of Selune, as if every foot of the game map is like a mile, it would take a week to get to the temple and a week to get back. How long does it take to discover that the place has way more goblins than they initially thought there was, to get spotted, and then start running for your life?
And let's say Aridan and his group were only able to make it to blighted village before they were attacked by goblins. That makes it even worse. Blighted village is closer. According to the documents found in the Grove, they left a month prior to the games start. So what were they doing for that whole month before Halsin was captured and they were chased back to the gate?
