Recommendations: Organize a strong war party composed of 8-12 players. Bring Ar and Pr gear for the majority of the mobs. If you haven't already, try the Chain of Rain before attempting what is meant to be a more challenging chain.

Bring 2,000 to cover the cost of the key. Purchase the key from the merchant and approach the essence of rain.

Island 1: Plunder the Fairy population until the Princess spawns. The Fairies will con yellow to a 60. The Princess will drop only two keys so it is suggested that you begin with a small raiding force of 8 and prepare to Coth the rest of your war party on the second, third or forth island.

Island 2: Speak with giant Efreeti to receive the quest. Only one person is required to log the quest. To complete the quest, defeat the gargoyles at the base of the ramp. If you are working on the level 59 Lava Storm quest, the Priestess is in the tower in Lord Efreet's castle. Speak with the quest NPC and an invisible wall will open allowing you to descend a stairwell. You can either fight down or invis and pass through. Beware of a trap hidden on one of the bridges which will crit for 6,000. At the end of the tunnel you will see a named mob which cons red to a 60. With a strong war party of eight you should have no difficulty defeating it. It will drop 8 keys which will allow you to advance to the next island.

Island 3: It is vital that you include an enchanter or bard in your war party for this portion of the chain as the mobs have an AoE mana tap. Also be sure to unequip your Ar as it doesn't appear effective here. In order to spawn the level 61 Whistling Wind you will need to farm the Whispering Winds. Once you have done that, you will need to farm the Whistling Wind to spawn the level 62+ Wailing Winds. After killing three of the level 62+ Wailing Winds you will receive one key. This may prove to be a time-sink for your war party as it will require you to continue to kill these mobs until each of the war party have acquired a key. The only other alternative is to allow a mage to use the first key and begin Cothing the rest of the war party to the next island one at a time.

Island 4: When you arrive equip Ar and Pr. The mobs have a nasty DoT and the resistances will help. If you are working on the level 59 Lava Storm quest, the Pristine Drake can be found here. The other drakes serve as a place holder for the Rancorous drake. Farm the drakes until it appears. Defeating it will trigger a astral essence. Port through and speak with the manifestation to assure that you have been flagged. Congratulations you have successfully completed the Chain of Sun!
