The Terrors of Iso'rath

For me, this quest was bugged. I was stuck on an island in The Maelstrom with Thrall. I couldn't talk to him or the NPC near the gryphon. I couldn't mount the gryphon, nor could I use my land or flying mounts. I couldn't jump off the edge of the island. I abandoned the quest, but there wasn't an option to pick it up again.

I hearthed out, and then flew back to The Maw of Madness. I was able to accept the quest again from Earthcaller Yevaa. After that, it was easily completed.

Note: If you use the Curse client, make sure all of your add-ons are disabled. In researching the bug, I found that sometimes the client can bug the quest.

Hope this helps anyone who was as confused as I was!

Here are the quotes I caught, first one being the one they say upon released. Should be a full list but feel free to add ones I missed, I stood there for quite a while but some of them took ages. Also included the one(s) heard during the next quest, Nightmare.

EDIT: And I get downrated why? I spent my own time to collect these for you all, just scroll down if you don't care.

Stormcaller Jalara:

"That foul thing got stains all over my new robes!"

"I command the power of the storm. It sounds impressive, but you wake up with static cling every morning."

"We command the power of the elements. Storm, Earth and Fire! I'd never dress like an oversized chicken and shoot moon beams from the sky."

"Many confuse the Earthen Ring with the Cenarion Circle. ...I TOLD Thrall we should name ourselves the "Earthen Square"."

"Shaman and druid ways are very different. When was the last time you saw one of us turn into a wild beast? ...nevermind."

"I think I saw something like this on the Exodar once..."

Earthmender Duarn:

"I'm... so... dizzy."

"To restore life is to restore the natural order of the elements."

"Few truly understand the shamanistic connection to the earth. It binds wounds, protects us from harm."

"I fail to understand why they banned totemic cleansing. No one was ever in range, anyways."

"Shamanistic healing is a complex art. You can't just chain heal all day."

Stormcaller Mylra:

"Thanks fer savin' me! When you passed out, I thought we were done fer!"

"It's about time we returned to the Highlands! "Twilight" be damned."

"When I said we should strike at the heart of the beast, going through it's stomach isn't what I had in mind..."

"I had a terrible vision - the sky was blotted out and there was dirt everywhere. ...I thought I'd gone back to Deepholm."

"The power of the elements is strong here. Little wonder this is where they chose to summon a servant of the old gods."

Hargoth Dimblaze:

"I thought for sure I would be this smelly beast's dinner!"

"Thanks fer saving me, laddie. I had a horrible vision. I was trapped in a cave of flame, forced to drop totems and heal irate warriors for years on end without seeing a single piece of shaman gear."

"Other shaman used to say, "Only yer offhand should be flaming." What were they going on about?"

"Do ye know how hard it was to find a set of weapons that matched me armor?"

"I can't wait to smash that old god brain between me fists!"

Did this last night and there is a method of sorts that makes it much much easier.

You are to kill the massive spawned tentacles while inside, however, kill the lower health ones first. Each tentacle you kill will save one of the shaman and each one of the shaman will fight with you until completion (and provides different abilities).

So try to kill lowest to highest health tentacles while making sure now and then to head into a nearby bubble for healing and removal of debuffs.
