Since Keith chimed in, here's an ongoing question from my group, STORY DESIGN wise, where does this adventure slot in? We feel its after 4-1, but trying to figure out story wise if it happens before, during or after 4-2.
Intent was before 4-2. That said, in terms of your journey, before or after both make reasonable sense.
In the middle of would be weird story-wise. Basically, both 4-P1 and 4-2 are in ports, but bouncing in and out of 4-2's while hot on the trail of something would be mighty strange :)
