My first thought is that we could go to Arachnid and inform Kumokogo about the incoming Orochimaru. That in and of itself could be easily squared away as 'offscreen, presumed done' but it also gives us the opportunity to follow up on a few Dragonwar threads that we haven't hashed out yet. Namely:
- What are Arachnid's neighbours, and what are relations like with them?
- How did the Hornets get to Arachnid, and does it seem likely that the Crusade might be able to follow the same route?
- Go explore Archaeopteryx island to see if we can find anything of use, particularly with our sealtech that the Arachnid scouts wouldn't have.
I'll let you know if I come up with anything for specifically within-Leaf, but
I really want to add more clans to the map I would be happy to see this in the next update, both because I've been itching to do
something for the Crusade plotline for months now and because exploring Archaeopteryx Island sounds cool.
