For the most time, I thought that Elbaf is straight-up Shank's territory but Lola's failed marriage with Loki pushes me away from this theory. It depends on when Lola and Loki supposed marriage happen. If it was way before Shanks was a Yonko then it's good and I would still pick Elbaf as Shank's current territory.
It could still be his territory possibly. Tbh, I think all 4 Yonko have a tie to Rocks in some way:
- Kaido/BM obviously do.
- Blackbeard or Shanks are "possibly" Rock's Son or some relation to God Valley.
If Blackbeard is his son, due to their similar ideologies and BB naming his ship after Xebec, Shanks may have been a God Valley inhabitant or some sort of relation to the Tenryuubito. It's implied that Shanks at least has been with Roger since he was born (Roger's whole "it's been a long time since I've held a baby") and Shanks being the exact age when the God Valley incident happened. BB being a year older supports him being his son as it could mean Rock's abandoned him the prior year, and why Whitebeard found him as an orphan.
Basically I can still see Elbaf being an entirely Rock's centric arc with all 4 Yonko if it panned out this way, however this would imply BM/Kaido survive Wano undefeated and someone like Yamato is the villain for Luffy instead this arc.
Who knows at this point, but I'd love all 4 Yonko to clash over something.
