Important Lore Missing: What Is Happening With Marucs Du Couteau???

With the last Noxus update with Swain, we got a little more insight into how Noxus works as a nation, and (some) of the champions' roles within it. Swain's new position towards Noxus and the Trifarix are all really well done, but one extremely event has yet to be touched upon; the disappearance/unconfirmed death of Marcus Du Couteau. The Du Couteaus in general haven't been touched in years save for Kat's new lore (which took Marcus in a direction that I don't personally agree with, but ok) and, the continued plot hole filled travesty that is Cassiopeia's lore (again, personal feelings. Cass has been my favorite champion lore-wise for several years, and I'm just frustrated with her being unfinished and ignored by the lore team, but I digress), and the fact that Talon hasn't been touched since the Assassin update 2 years ago. TWHO WHOLE YEARS. (I get that you guys are busy working other stuff, but two years? Come on...)

Marcus Du Couteau and the Du Couteau family as a whole are huge players in the Noxus lore, but we've been given next to nothing about them for so long. A lot of us fans were really hopeful to get an update with Swain's rework, but were incredibly disappointed in what we were given (or lack thereof). We would like something, anything about what's going on with such an important aspect of Noxus' story. What was Noxus' reaction to such an important figure's death? Is Cassiopeia still slumming around in the crypts and killing at night? Has she reached out to Katarina or Talon? WTF IS HAPPENING WITH TALON ANYWAY?!?! (SERIOUSLY, TWO YEARS?!?!)

I'm sorry if I sound short and impatient, but it's because...well, I am. I've submitted several Ask Riot questions about the same subject, and I've just gotten ignored. I hope someone will actually see this here and give us die-hard Du Couteau fans some desperately-needed answers.
