Yes, Vinculus as the one who created the cluster is perfect. Plus you have him popping up in the most inconvenient moments like Jonas (ESPECIALLY with Norrell because that is comedy gold I mean come on).

And I 100% agree about Flora needing to be in more things. I'm desperately casting about for more female characters that could be a part of the cluster. The ladies of Grace Adieu?

What about Grant/Hadley-Bright (not female I know, but)? They could do with a fighter...
