I was doing solo Crota each week with a fraction of lost hope for hawkmoon. I hit the jackpot and got g horn from death singer twice in a row from different characters. On the next character however, the hawkmoon dropped. Happiness and joy. But that wasn't the first time I got it. The first time was during Sepiks void burn. First time with void burn. That's when me and my buddy I met in patrol destroyed the servitor. He got a thunderlord. I got the Gjallarhorn. I did not know its power back then. And was more into the thunderlord. That is until I unlocked the exotic Wolfpack rounds. There, I knew how powerful this beast is.
