There are a few things in data bank notes that I think could be fun to learn more about:

• Xin-41 Homeward Cloud Messaging and Researcher Eikura Shuu's Diary have mentions of a world that could be interesting to visit, even as an aside. This is particularly because there could be so much to develop around the Slinkans and their oppression of people on Xin-41.
• To look into Polka Kakamond, here are some additional information sources: Digital Save of Klein's Handwritten Notes (Excerpt)
• It states that Diamond reclaimed the lost world of Jarilo-VI in the Ten Stonehearts faction entry, but that seems contradictory with the story that we're playing because Diamond was not part of that project at all (and Topaz didn't truly reclaim it, though she did succeed in building the connections for revitalisation).
• Who is this Adrian Spencer Smith person? It'd be nice of the game to provide more access to them, as they are continually quoted in many different entries for aeons and factions (AEONS: Akivili, Nous, Qlipoth, Tayzzyronth, HooH; FACTIONS: The Nameless, Elixir Seekers, Antimatter Legion, Lord Ravagers, Genius Society, Garden of Recollection, Mirror Holders; CONCEPTS: Eden of Blessed Insight).
• It'd be fun to return to Jarilo-VI to either help rebuild or do archaeological digs at other places to add to the museum in Belobog. There are mentions of Nycatha in Jarilo: God of Spring and War and also Ice Storm Causes, so it could be interesting to go further out to explore… Perhaps with Lynx.
• Probably a good idea to put together the Genius Society's members, like Sserkal.
