Mark this post as read if you want to remain in the dark.
For every one else, I had the screenshots in my library for quite a while.
It’s no fun listening to audio streams and listening to “Oohsâ€Â, “Ahhsâ€Â, and applause without getting to see it.
Check out the last shot, too. I don’t know if anyone’s ever mentioned that yet before. I found it interesting.
So here’s a few shots of Eye of Eternity, Obsidian Sanctum, Halls of Lightning, and Storm Peaks
Left: Here’s a shot of Malygos in his humble abode. The raid instance is literally a giant disc with Malygos flying around until you activate him. It’s a 3 phase encounter. I haven’t successfully completed him yet so I can’t offer much at this time.
Right: Me in my awesome attempt to try and do something. Alas, Malygos is overpowered and promptly kills us a matter of minutes.
Left: This is a shot of Obsidian Sanctum. Here is a shot of the party engaging the mini-bosses.
Right: You’ll notice the phasing mechanic put in play. Even though it “looks†the same, I get thrown into a different dimension. Here, I have to kill that shifted drake along with the Rogue or else something bad happens. I don’t actually know what.
Left: We’re taking on Sartharion. The guy hits like a pansy. For the raiders, take a good look at positioning in terms of tank, boss, and group. There’s a good reason for it.
Right: … Because every so often, a big wall of fire is going to rake the island that we’re on. Notice there’s a hole. Right when the wall warning occurs, the entire raid needs to ensure they’re in one of the two “safe zones†(on the left and on the right, by his tail, if you look carefully). If you eat the fire, you get knocked back and take a non-pansyish amount of damage.
Left: One of the old guys, I think. Wouldn’t dare hit a Dwarven brotha’ from anotha’ motha’. But I don’t dare test out my hypothesis.
Right: Another shot of the exterior. Place looks b-e-a-utiful.
Left: Interior shot of Halls of Lightning. See those Dwarves on the left? It’s the Terra Dwarva army, baby!
Right: The roving boss that was mentioned in the D & R panel is this guy. We decided to set him up in the corner. There’s me with the lightning debuff (Pro tip: When you get it, don’t move. Trust me.)
Left: Lastly, check out this interesting shot. It’s right after a wipe and after I released spirit. When you died in Tempest Keep, you’d automatically res to full health and life outside. But if you die out in the Halls, you seem to res in spirit form while mounted on Ghostly Gryphon.
And that right there is the gimmick for the fight. I like to designate left side as positive and right side for negative. You don’t have to stray too far out. Melee players with opposite charges can remain 180° from each other and still stay within striking range of the boss. 
Healing is a walkover on this boss. AoE heals and single target heals on the tank should the order of the day. Your AoE healers will be able to cover both groups no matter which side they are on. Keep a single target healer on the tank at all costs. He does like to randomly fry players with lightning. It’s nothing a healer can’t handle, however. 
The AoE healer will be keeping an eye on the kiter. It is inevitable that the kiter takes a few glancing blows here and there. Every time a player gets hit by Zombie Chow, they suffer a disease called Infected Wound which cannot be cleansed. It wears off after a minute. The disease causes players to take increased physical damage by 100 every time it is applied. I once had 20 applications of the debuff and believe me, it wasn’t fun at all.
