So when the owl sector thing was big and everyone played, those who played and received the crucible buffs also received the Owl Sector Emblem. I played and got all the buffs (no exaggeration) before the emblem was given out, and my friend only got one buff (which i got for him haha). My friend received the emblem and when i went to check my postmaster to get the emblem and low and behold 'twas empty, no emblem in sight. i thought that was weird, so i checked the emblem kiosk and it was not there for me to get. I know its really late to bring this up but with destiny 1 coming to a close this year i want to make sure i have as much as i can get, and the owl sector emblem is one of those that i should have gotten but didnt
Unfortunately it looks like you either did not participate during this time period, or you did not get an infection as you do not have the Transmission grimoire card unlocked. Regardless, there is no way to receive this emblem anymore.
