I'm guessing Neptulon's fate will be revealed in the future Azshara expansion, i'm crossing my fingers for an underwater expansion
For the second, I don't think it was ever stated, but it was heavily implied that it was the Old Gods that turned them into Naga, and throughout Vashj'ir, we see the naga working alongside Old God minions.
Neptulon... well... he was....
He appeared, we fought beside him, he was sucked up by a giant octopus... and nobody spoke of him again...
Sometimes Blizzard cares more about making a 'cool' story than they care for logic.
Yeah, it was an odd "ending" for him on that page... But if a expansion comes out involving the rest of the Naga rulers and realm, and the South Seas - then chances would be high to see him back.
Stuff can be fixed, just get enough glue or duct tape!
Roses are red, mana is blue. Suramar Guards, Will always find you!
I see a lot of people saying that Neptulon was abducted after the events of Throne of the Tides, he was abducted prior to the events of that dungeon which is why he is trapped there and the purpose of going into it is to save him from the Naga and Faceless. Happens at the end of one of the quest chains in Vashj'ir.
Aye, I'm with you Apathy. I was sorely disappointed when Blizzard scrapped Abyssal Maw... I really thought it would have been good to have Firelands and Abyssal Maw launch in 4.2, that shit would have been absolutely awesome.
Such a damn shame. Hopefully Blizzard will revive the story. =/
There was originally going to be a resolution to this in a raid alongside Firelands, the Abyssal Maw raid, but it was cut for time. So it's ultimately unresolved.
