A mysterious woman by the name of Senturi has visited Evermore and she claims it is her destiny to serve the One True King. However, before Evan can claim this title, he needs to overcome a test, to defeat the Starless Knight. This Tainted Monster is located inside of the Bleachbone Shrine, which is located southwest of the Drylands trip door. Enter it and go to the last room, where the level 66 Starless Knight will be waiting. As you will see, it is one of those skeleton enemies, so adjust the Tactics Tweaker accordingly. Defeat the Starless Knight to receive Songbook No. 22, then report back to Senturi to finish the quest.
