I don't know about hardest but here goes. Kabr's I'll fated VoG experience and Eris's botched attempt on Crota, when did these take place relative to the beginning of the game? I am still unsure about the timeline between the collapse and guardians becoming a thing, I have heard guardians came about post collapse but don't know for sure. So were these well known "adventures" involving now widely talked/rumored about guardians centuries old? A couple decades? Years? Also when I read the grimoire it comes off to me as all happening at roughly the same time. Am I waay off base with that? Finally good job with lore posts the CoK is great Anonpig did a great job getting the ball rolling and it is nice to know there are more people picking up some of the weight to spread interesting lore.
