Level 120 Cygnus Quest Guide?

I had the level 100 mount. The mount isn't free and isn't part of the quest that you get Echo from. Shinjo is another quest, just like each of the level 50 and 100 mount quests are their own. You have to give 50 mil to that guy who gave you the level 50/100 mounts, then go to the dragon by NineHearts (isn't his name Shinjo too?) and he'll/she'll give you the mount.
