This is a long line of quests in EverQuest II's Desert of Flames. Most of the quest line is soloable, although the later quests have some heroic steps. This is a recommended quest series for soloers at levels 45-55, as it's one of the only that takes you deep inside a dungeon (starting with A Final Note). Ultimately, the Peacock Club timeline will result in an epic raid in the Fountain of Life, which rewards you with what is being called a "T6 Prismatic" or "Prismatic 2.0".
