Take the second left when running through Noble's Causeway from Dranik's Scar to Wall of Slaughter. After that leff, you will come to another bridge and as you approach it, a small fire elemental named Siflu will spawn on the other side next to a boulder. He’s a blue con at level 70, but doesn't see invis, nor do the 2 roaming Dragorn that path past him. In addition, those two Dragorn roamers do not assist Siflu if he’s aggro.

Engage Siflu and you will receive this emote:

The Heartwood Blade thrums as you battle the flame spirit.

At approximately 10% health, Siflu will go non-combative.

Siflu says 'Well, that was interesting! I guess you've broken their power over me. I suppose I should be grateful or something. I was having fun here, killing people without having to worry that it might be wrong. So what is it that you want from me? You're not going to yell at me for beating up [adventurers], are you? That wasn't my fault, I was forced to do that by the muramites.'
You say, 'adventurers?'
Siflu says 'There have been plenty of those, that's for sure. If you mean recently, then, I suppose I know the group you're talking about. They were hunting us, just as I suspect you are. I was sent to kill anyone that might be on our trail. They gave me a loadstone that I could use to find them again. Here, you take it; I'm getting out of here while I still can.

At this point you receive Heated Loadstone and Siflu despawns.

Moving left along the zone wall in Wall of Slaughter from Nobles Causeway is a series of buildings. If you have the Heated Loadstone from Siflu, as you approach the buildings, your loadstone will give you a yellow emote text and A Mangled Muramite Captain and 2 Ukurn guards will spawn. The Mangled Captain is red at level 70 and the two Ukurn are blue. The Ukurn can be bard split from the Captain, so a single pull is possible.

Kill the Mangled Muramite Captain and receive Traverler’s Journal and Spirit Manacles

The Traveler’s Journal says the following over 4 pages:

"We have learned a few things. The Muramites are definitely capturing people and making slaves of them. So far they haven't caught too many of us since the Wayfarers opened the portal. Mostly they seem to have been taking elementals. Not sure why. Hopefully we'll have some real information to return to the Brotherhood officer when we are done here.

We're on their trail now. Rolf managed to get close enough to them to notice that they had a fire elemental with them. He says there are only four of them, the elemental, two flunkies and some sort of leader. He heard the two flunkies talking about how it would be when tehy were reinstated into the army, so it sounds like these are independants. Their leader appears to be permanently injured. Rolf says that they talked about his failure at a trial of some sort adn how they would get a chance to earn another try if they brought the big cheese enough slaves. We shouldnt have any trouble taking them out, they appear to be failures on all levels."

She hits for 2500 and single rampages. Over the course of the fight she will summon three lvl 70 fire elementals - Flamegore, Sizzle and Hotspot.
They are able to cast Heatwave (1500 AE) and Balance of the Nameless (Dispel). They hit for an average of 400 and are mezzable.

After the last add from the first wave is down, another wave of five elementals will spawn: Cinder, Coal, Flametop, Flareup and Burnscar. These are blue to lvl 70, hit for about 390 max and 170 on average and cast the same spells as the first wave. These are mezzable as well.
