Fandom PSLs

Late as usual to the bandwagon, I'd love some PSLs in The Expanse fandom. Ignoring the journal, I'd love to write Camina, Holden, or Bobbie. I'm open to writing against other canon characters, cross-canon, or OC's. I have ideas, depending on who I'm writing against! I'm good taking it from during or after the series, with a slight preference for after unless doing backstory scenes with canon characters.
