Since I don't see a thread started yet for this one I figured I would get it started.
A Bard's Song is a new Limited Time Event with what originally looks like only 7 parts but once you get to part 3 it branches off into three 4 part quests to search for Runes. Part 6 also branches off into two 10 part quests. More to come as we find out more.
