Azsuna is located on the West/South Western side of the Broken Isles. A land rich in magical leylines and magic so condensed that it has formed crystals. Azsuna was a home to many elves, nightelves and highborne.
Azsuna is a very serene place, with mythical beasts that adorns it's plains. However is seems some of the Legions corruption has begun to take a bit of this land over. You will aid this land and those that currently reside in it by thwarting off some of the Legion as well as helping out a familiar dragonflight. The magical academy is also located here as Azsuna is a place that does hold vast amount of magic located in it's leylines. You will also learn about an old foe that you once fought during one of your trips back in time to the well of eternity.
In Legion they are introducing dynamic questing. Essentially this means that the zone you are in levels with you or you level with the zone. No matter what level you are the zone will scale to you, the player. This means you are able to choose whatever zone you wish to quest in without worrying about out leveling the zone or having it become irrelevant to your level.
To start a zone all you need to do is venture to your Class Order Hall and open up the scouting map in your missions table and select the zone. From here you will be given a starter quest to go to Dalaran and then it will lead you to the zone.
There are many rewards you gain for completing a zone. Toys and Pets are unique to their zone, but something all zones do share is vast amount of Artifact Power. However the amount of Artifact Power you get through questing and hidden treasures varies a little bit.
Completing the Zone, ensures the max artifact power gained for that zone. If you would like to make sure you didn't miss out on any Questor's Glory check the list! This also ensures that you work towards Loremaster of Legion which unlocks an artifact skin!
The main questlines required for Azsuna Matata are:
In working through a zone, you do earn quite a bit of Reputation with the faction for that zone. For example Azsuna rewards you with Reputation for the Court of Farondis. If you start fresh in this zone, you can finish the zone with honored reputation simply through questing. You will also complete the achievement for this zone which is needed later for when flying becomes available.
When you become honored with the faction made for that zone, you can unlock a Treasure Map: Azsuna from the quartermaster. This map will help you see hidden treasure boxes located in that zone that you may have missed while leveling. Discovering treasures is required for Treasures of Azsuna.
Most treasures in Azsuna rewards Artifact Power items, Order Resources, Champion follower gear, and some vendor trash. This is different from Warlords treasures where each treasure had a unique reward.
Zone highlights for Azsuna is learning about the Academy of Magic that many aspiring wizards had to go through. You also aid in a familiar friendly dragonflight as well as learn why they are even here in Azsuna. The dungeon Eye of Azshara as well as Vault of the Wardens is located in Azshara. The world boss located here is Levantus.
