I got mine from xur. Weird though. I got the emerald coil and equipped it on my timebreaker. Went on patrol to try out my new ride...hit the thrusters and was flying around like a madman. All of the sudden the damn p.o.s. emerald coil malfunctioned causing me beloved timebreaker sparrow to explode! I was so pissed. But then in the corner of the scteen an exotic bounty showed up. I took the broken pieces of my sparrow to the shipwright. She gave me a RED mote of light to take to the speaker. I exchanged the red mote with the speaker for a broken accelerated coil. Tiok the broken accelerated coil to the REEF GUNSMITH who only appears on sunday at 10am to 10:03am and exchanged it for 3 vex mythoclasts. THAT.. .is how I became legend.
