Here's chapter 1 from Leviathon:
It begins with the Aspects and other better known dragons meeting below Wyrmrest for an accord. Chromie mentions that there are problems with the timeways but Nozdormu silences her and tells them that the timeways are now out of his control and that it now falls to mortals to handle it and only them. Ysera's daughter Meritha then mentions that the Nightmare at the Rift of Aln is acting up but Ysera says that handling the Nightmare now falls to the druids as they can handle it better than the Green Dragons as she too lost her powers.
So yea it seems the dragonflights did lose their abilities.
The dragons then begin bickering when Kalecgos goes to speak with Alexstrasza saying it would have been disrespectful if they didn't meet at the current cycle of the Twin Moons to which Nozdormu asks who it'd be disrespectful too. Elune which the night elves worship? To the titans or their servants when they don't know if the Titans even exist anymore? It surely is not disrespecful to the dragons and he says it is best to put the Accord to a rest and move their own separate ways and deal with their own problems. Kalec mentions how the point of accord was to be united but then Ysera brings up Neltharion and Malygos to show how well being united worked while even making a glance to Nozdormu who says it's best to not leave him out but that accursed dragon was his far future self but he is to blame for his evils just as Neltharion was to blame for what he did as Deathwing to which Alexstrasza mentions that the future has been altered forever after he fought his future self and that he should not mull over it. But now they are no more powerful than any other dragon and the time of the Aspects has passed and so has the Wyrmrest Accord. Kalec tries to mention how they are still the leaders of their flights but Ysera and Nozdormu still leave saying that their time is done and that Azeroth must look to other defenders.
Kalec then says if they want to end the Accord than they shall do so with the proper respect and meet again in 1 month. After they all leave Kalec is left thinking to himself about what had happened there and thought it may have been better if he stayed in Dalaran as Khadgar suggested and join the Kirin Tor. But in the end he had made excuses to Jaina saying he needed to oversee the crumbling of the Nexus' defensive spells. His own dragonflight has all but fallen apart and that he has also failed as the leader of the Blue Dragonflight with the Nexus now becoming a place of emptiness. He still felt ashamed at his failure to prevent Theramore by finding the Focusing Iris and what it caused to Jaina. But even with all this misery he was not ready to die yet in the frozen wastes of Northrend and flew from Wyrmrest. Being a Blue Dragon he still was more attuned to arcane magic and sensed something nearby and found the remains of Galakrond and flew towards them.
That's the end of chapter 1.
And then from me, here's chapter 2:
Couple things from chapter 1 I didn't see Levi mention:
-Ysera sarcastically suggests all of the Aspects start hanging out in their humanoid form with nicknames to finally bring an end to their era. She then states that she has spent more time as a night elf than a dragon lately.
-Naralex led some druids to deal with the Nightmare. This might be his quests in South Barrens or it might not be, idk.
-The Aspects don't think of themselves as Aspects anymore. They only think of themselves as three big dragons, among hundreds of other dragons.
-Afrastrasz was sympathetic to Kalec voting to keep the Accord, but everyone else wanted it gone.
so chapter 2:
Kalec lands at Galakrond's Rest, with a little fear that Galakrond might suddenly burst to life and eat him. He had never felt this weird magic trace before even though he had been to this part of Dragonblight more than once. He uses some magic sphere to melt away thousands of years worth of snow then scrapes away at the hole it made to find whatever is hidden beneath.
He suddenly sees:
-A yellow protodragon arguing with an orange one.
-A robed humanoid with one arm visible.
-A white protodragon shrieking as it shrivels into a skeleton.
-A dragon, faint bits of green skin, charging at Kalec with flesh hanging off rotting bones.
Kalec screams and stumbles back, crashing into Galakrond's ribcage. He felt like the visions were real but none of them made any sense especially not the last two. He starts digging into the whole again and a lavender aura raises from it. He finds an octagon-shaped object made of a metal he doesn't know. It changes from looking like gold to looking like iron depending on how he held it. The lavender aura surrounded it but was separate, like clouds over a globe.
He tries to probe it but the aura fades, and now the magic emanations have stopped too. He leaves Galakrond holding the hexagon tight, and as he leaves he looks into Galakrond's empty eye sockets. He would use the artifact as an excuse not to think about his most recent failures. He sees Wyrmrest Temple and hisses, because it no longer means anything for him. It just represents the future he had once thought awaited him as an Aspect.
At the Nexus, two blue dragons leave and head south. Kalec doesn't know if they ever intend to return. An old dragon named Jaracgos meets Kalec and calls him Spell-Weaver but Kalec says that's no longer his title. Jaracgos says he was glad Kalec returned because he would have felt guilty leaving without telling him. He promises to return on occasion.
As Kalec walks through the Nexus he hears "Do not argue, Neltharion!"
"I do not argue! I fight!"
Then he sees a young yellow dragon and a high peak that looks like the ones in Storm Peaks but isn't as weathered by time. He hears a female blue dragon calling to him in the distance, then hears a roar and realizes it's him roaring.
Cut to Malygos as a blue and white protodragon, flying over the sea and thinking the hunt had been good. Kalec suddenly thinks in Malygos' mind, reminding himself who he is and wondering what's happened.
Malygos sees another protodragon and starts to seek it, despite Kalec trying to make his body fly back to Coldarra. It's not unusual for protodragons to challenge others for dominance, and Kalec wonders how he knows that. Kalec doesn't know how he knows this protodragon is a young Malygos.
Malygos roars at an orange proto dragon, but she yells she means no harm. Kalec wonders how this one could speak, and thinks apparently some of them crossed the threshold out of mere animals. He thinks this is the same orange protodragon he saw in a vision earlier.
Malygos says "No battle," agreeing with the female orange. The orange is looking for her missing clutch brother. Malygos doesn't see any other orange ones. The female has nowhere else to look.
The female know where he was but not where he went and Malygos says to show him. They fly to a rocky landscape and a grey protodragon charges out, Malygos growls at him, but the female says "No enemies!" Malygos says "A waste! He is a stupid one! Not smart!"
The gray one roars and the shockwave sends Malygos flying back. The gray pursues and Kalec thinks this one is more like protodragons he's used to. After they fight the gray flees, and the orange female says the gray was scared and he didn't want to fight. But he gave no choice.
Malygos says "Very supid beast! Not smart like me! Not smart like Malygos!" and the female agrees, that he is smarter than her. Malygos says "I am smart. I will find your clutch brother, Alexstrasza."
Alexstrasza wonders why the gray one was scared, Malygos shrugs (somehow). Vertigo overwhelms Kalec and now he's seeing a different time period, still from Malygos's point of view. A mournful howl raises next to him, and Alexstrasza is letting out the cry. Alex's brother is dead. He was nothing more than a shriveled mass of skin and bone, and Kalec has no idea what happened to him. Malygos shivers but doesn't know why.
A shadow blankets then, something high above. Before Kalec could focus on what he saw, his surrounds turned chaotic full of voices, roars and brief images. Then he blacks out.
