[Speculation] Anduin's lies, Saronite and the World Trees.

TL;DR at the end.I posted a map of the possible location of N'Zoth a few days ago which got some traction, so I've decided to get some other thoughts down about the possible future of our dear Azeroth and how things may come to pass. The main focus of this is on a few of Il'gynoth's whispers and a new interpretation of them."Her heart is a crater, and we have filled it.""The king of diamonds has been made a pawn."We receive "The Heart of Azeroth" from Magni (who is clearly the King of Diamonds) right at the start of BfA and immediately start filling it with Azerite, a mysterious, massively power dense ore made from the Blood of Azeroth. That stuff sounds awfully similar to Saronite, the solidified blood of Yogg-Saron that drove people insane.So, we have Magni giving us a "gift" from Azeroth for protecting her and are asking us to fill it with something that he promises is Azeroths own blood? I don't buy it. The Old Gods, for whom Magni really speaks, are using us to empower an artifact with Old God corruption. To what ends they would use this artifact i could only speculate, but I doubt we'll enjoy it.Five keys to open our way. Five torches to light our path.Its surface blazes bright, masking shadows below.The World Trees are pretty damn mysterious. We know they used to be the font of the Night Elf's immortality once blessed by The Aspects, but not much else. They're based on the Norse Mythology of Yggdrasil, a World Tree which trapped a dragon, Nidhogg, beneath it's roots and provided a place for life to flourish. Again, sounds pretty familiar. Now one of them has mysteriously burnt down. We're made to believe The Horde did it, but if it was to be that transparent, I doubt it would be steeped in mystery from the off.We have 4 world trees confirmed to exist in our realm on Azeroth, and a 5th that's a little more ambiguous, but we've encountered it all the same.Nordrassil - Mount HyjalTeldrassil - North east of Kalimdor, home of the Night ElfsVordrassil - Grizzly Hills, Northrend. Torn down by ancient druids because its roots reached into the prison of Yogg-SaronShala'drassil - Val'Sharah. Links directly to the Rift of Aln, where we fight Xavius and find the "Remnant of the Void".Un'Goro Crater - World tree corrupted by Il'gynoth himself. Seems to only exist in The Dream.Using the Norse mythology that they're based from, as well as some other hints in game, I'm pretty certain these 5 World Trees are playing a big part in keeping the Old Gods at bay.That would make them the 5 keys, and by destroying them, say, by setting them on fire ("It's surface blazes bright"), they would also become the torches that light their path.The boy-king serves at the master's table. Three lies will he offer you.The Old Gods draw power from death. Xal'atath, the Shadow Priest weapon, bangs on about it quite a lot, so something like a world war would only serve to empower the Old Gods on their return, as well as weaken any opposition. Thankfully Anduin is all too happy to oblige.The three lies he will offer will be the lies he uses to justify his crusade:The Horde abandoned us on the broken shoreThe Horde burned down TeldrassilThe Horde... Watch this spot.Anduin is literally serving power to the Old Gods on a silver platter directly to their table. He's not choosing to help them, but in sparking this conflict, it directly helping them return to power. He's serving Azeroth to them.The Old Gods are coming, and N'zoth will be the first to rise.Battle for Azeroth is the staging ground for their return, seeded by their corruption, whispers and meddling throughout Legion and previous expansions. We, just like the characters in the game, have no inclination that they're about to return. Our focus is on our own petty conflicts, conflicts that were steered and driven by the Old Gods.They're playing the long con and they're almost ready to kick off.TL;DR:Azeroth's Heart is given to us by Magni, a pawn of the Old Gods, who asks us to "empower" it with Azerite, which is too familiar to Saronite, the blood of Yogg-Saron, to be a coincidence. The 5 keys that unlock their prisons are The World Trees, steeped in Norse mythology alluding to a similar story, The Torches that "light our path" are these very same trees burning to the ground. Anduins three lies are the justifications he gives to his people for his crusade against The Horde, two of which have already come to pass: The Broken Shore "abandonment" leading to the death of his father, and the burning down of Teldrassil.
