“didn’t you ask something like this earlier?” yes. I’m going through naming a lot characters right now, many of whom are related to someone who is obsessed with legacy/honour names.
anyway yeah ! Bessarion is cool af but it’s a little on the nose. Also, please feel free to throw some absolute batsh!t names at me, it’s a free-for-all up in here. I just need something that preserves the vibe [and sound!] of Bessie.
Edit - Thinking about maybe Bailey ? That or Esben
Esson? Is that a name? 
[name_u]Beck[/name_u] came to mind first, as well! I think [name_m]Seb[/name_m] could also work.
Maybe…
