==Walkthrough==
This walkthrough is for normal mode. Experiences on veteran mode may differ.
In Rockgrove, you will find an Argonian named Dust-On-Scales. He will tell you that the xanmeer here has been overrun by the Sul-Xan, who are trying to summon the daedra Xalvakka by feeding it souls. His apprentices stayed behind to fend off the attackers, but were not heard from since. He will then ask for your help in stopping the Sul-Xan.
Head through the gate to the east, to the Overgrown Thoroughfare. As you engage with the enemies here, take care to stay out of the water; it will damage you. With regards to the enemies in this dungeon, there are three types: the soulreavers should be lured away from the group and dealt with once all the other enemies are down. They like to throw AoEs around but these can be evaded without too much difficulty. The Death Hoppers are frogs who will target random players regardless of being taunted. The reavers are very strong; take care to avoid their light attacks. Bloodseekers are sinimarly strong, but your true priority should be in taking out Havocrel Torchcasters whenever you see these. 
Proceed along the path and dispatch any mobs along the way. If you head northward, you will see a group of wounded militants up ahead. The moment you engage with them, a miniboss will spawn; Basks-In-Snakes. True to his name, this guy likes to summon hordes of snakes to his aid, but these are not hard to defeat. Just press the attack and Basks-In-Snakes will die. 
Head back and towards the Xanmeer. In the south of the area, you will find the door to the Ruined Springs. The first boss awaits behind this door; Oaxiltso The important thing to take heed of here is the poison mechanic. Every so often the boss will poison a player, which deals damage over time. You know you have been poisoned when your screen turns green. If you have been poisoned, head into one of the pools in the corners of the map to cure yourself; the pool will become poisoned and spawn some Death Hoppers, which must then be dealt with. This boss also likes to spawn a Havocrel Annihilator to help him; take this thing down quickly.
Once the boss has been defeated, head on into the Xanmeer. You will have to fight through several rooms full of enemies inside, some of which can be tricky. Make your way to the top, then through the door to face the second boss, Flame-Herald Bahsei. When facing this boss, you will notice the Oblivion Gate in the far right corner of the battlefield. This gate is of little relevance in the battle itself; the boss likes to spawn daedra to help her, but they will not come from the gate. These additional daedra like to use area of effect attacks, but they can be lured into their own area of effect to damage them. Kill the boss's allies when they spawn; focusing on them is important to avoid getting overwhelmed. The boss herself likes to curse the players furthest from her; this will cause explosions that hurt all players in the vicinity. Take care to avoid the blast. At a certain point, meteors will start falling down; watch out for areas of effect. These meteors will contain a sun that must be destroyed as quickly as possible, lest they wipe the group. 
After you defeat Bahsei, his soul will be drawn into the oblivion gate; you will hear Xalvakka's voice proclaiming that she is coming. Dust-On-Scales does not know how to close the oblivion gate from the outside; he will ask you to head in to defeat Xalvakka there. Head through and you will find yourself in Mehrunes Dagon's Deadlands. Head along the path; you will have to face some enemies along the way, including a miniboss called the Ash Titan. This miniboss will have two daedra to help him; focus on the daedra while avoiding the meteors, then shift your attention to the main boss once the other enemies are dead
Head on after defeating the Titan; you will see a tower up ahead. As you cross the bridge, you will see Xalvakka herself appear on the ground floor of the tower. Head over there and start the fight. She has an attack that will deal 5 hits; the main tank should try to avoid as many hits as possible, though it does not matter if you get hit one or two times. She will also summon ghosts and daedroths to her aid; kill these as they appear. Occasionally, the boss will get a shield around herself; to dispel this shield, . Once the boss is at 70%, she will head for the stairs; follow her, for this floor will soon be one with the lava. There will be fire traps on the staircase; you can take as much time as you want avoiding these, as the staircase will not fall under the lava. On the second floor, the fight will mostly go the same as on the ground floor, except that the boss has one new attack. She will split into three and cover the ground with an area of effect damage. The two copies will be see-through when you approach them; focus your damage on the real boss and she will eventually stop the attack. Once theboss drops to 40%, she will again head for the stairs to the top floor. Follow her, same as before. This final battlefield has a giant hole in the middle; take care not to fall in. It can be difficult to see the floor when the boss is doing her stage-wide area of effect, so pay attention. She will also start throwing fireballs at you. 
Once Xalvakka lies dead, the souls of the people will be freed, and you will be teleported back to Rockgrove. Speak with Dust-On-Scales here to finish the quest.
