My basis for his headcanon is when he yelled "Surik's Blade!" As such, a cool easter egg would be Sskeer teaching Keeve about that era and mentioning Qyzen Fess, a legendary Trandoshan hunter, and his Jedi partner, the Third Barsen'thor.

Though unlike Qyzen, I doubt Sskeer worships the Scorekeeper, the Trandoshan deity, and keeps Jagannath points because he is a Jedi. Not only do Jedi not hunt people, but Sskeer has anger issues and is afraid of hurting those he loves, so hunting people would only worsen his issues. Though I can see him being respectful of his people's culture.

What. An. Opening!

Here’s hoping the rest of the book can follow those first 124 pages!

Light of the Jedi by Charles Soule

Chronicles of the Jedi is a lovely book over the complete high republic era.
