On a whim, I took another stab at the Silverwing quests tonight instead of doing HoH for the zillionth time, and actually managed to find some of the pieces fairly quickly. After running around Droga, Noble’s Causeway, The Deep, and Velketor’s for a while, I had three more pieces: the belt, cloak, and mask. The belt and cloak were even decent upgrades, which is going to make giving them up to make the charm even more difficult…
I also ran across an old friend from the very early EQ days, when I had a small, regular group I played with a lot. Looks like the mercs are bringing back even more people.
