Honestly, Kela De Thaym getting high because of a gas leak and inventing Lathuum (a rathuum variant with "acid throwers" filled with water instead of acid) was probably the most hilarious event so far (even if Dog Days is yearly), and my personal favorite tidbit about the Grineer (mainly because it is hilarious in context and out of context)
Techrot (the Infestation strain introduced by 1999 that we've only seen in dev streams since 1999 isn't out yet) seems to predate the Derelict strain, but it could also be a genetic ancestor to technocyte as a whole assuming it isn't a retcon to the Orokin inventing the Infestation.
Trying to keep up with the story can be confusing but I gotta say I love that I can still play through each story instead of having content sunset like destiny does. I took a break from destiny 2 for a while and when I went back there was full storylines I couldn't playthrough because they were removed so I had to skip a bunch of stuff it was so infuriating and I ended up getting into Warframe instead
