#2. I think you may want to try to agree this between captains. You can send two ships after one adventure, no problem with that. Those that get it for D5 may wait for the next time till the others get their chance for D6, to ensure some rotation and not make exploration a domain of just one boat. By crew I meant PC crew. Your DP crews are still there, but ships have to be commanded and manned by NPCs. I won't run a module for less than 3 active PCs I won't have to ghost through it. Particularly because if it doesn't finish by day's end we have a problem of it stealing timeslots of roleplaying for the next IC days as people hang in limbo, something I will want to avoid at all costs, aborting the module included.

So before you declare exploring, commit to it. Organise a team that can hop into it on first RL day of an IC day and proceed dynamically. For now, try to organise first foray for D5. Let's say West Port boats and Yamato are free to participate in it, Sui and/or Susu would do good meeting Juanito, Fuad, Mahasin or Goncalo to get their clearance. But it's also affected by the Tension dynamics. The more gaijin like you, the more freedom you have. Well, you can also just try to take your boat and leave port without clearance. It's possible, but will have story consequences.

Susumu, we need to meet with someone D5 to be able to go exploring D6

Berena is not available for this adventure, so if Edogawa wants to ship out with Keiji, he'd be welcome? It's not like they've ever accidentally sailed into the wrong dimension or anything before, right?
