Before the draft, the Malnosso weren't the type to tell us anything. After the village-wide memory loss, they wouldn't tell us much of anything. But they've been forthcoming since they realized they need us for their fighting.

If we fight for them, not only do we get to get a chance to see the world outside the barrier, but we get to see who their enemies are. We might even get a chance to get information from that third party group. We'll have a chance to see their facilities... and if it comes to it, to escape from the village altogether.
