Phase 1 is the top of the Vault dungeon against Heavensward. Haurchefaunt saves you but dies in the process. Next fight is against Thordan. Defeating him leads to Nidhogg/Estinien fight. Finishing these, the wandering minstrel is like “yep that’s how it happened, but what if you could save your friend?” and he sends you back to the first fight. But now you have LB3 banked and can use it to save Haurchefaunt. This leads to the minstrel going “ah yes, a friend saved, but at what cost?” Without Haurchefaunt’s sacrifice the WoL doesn’t follow Thordan to Azys La immediately and Thordan succeeds in eating the Warring Triad and absorbing all of their power. Estinien tries to stop him but fails, and in his weakened state is possessed by Nidhogg. You now battle against a powered up Thordan who is going around tempering dragons and turning them into his new Heavensward. You defeat Thordan and he begs for his life, but you kill him. You then move on to battle Nidhogg and an enslaved Hraesvalgr, which Nidhogg has enthralled using Allagan technology. You defeat them and Estinien overcomes Nidhogg BUT THIS TIME because the ghosts of Haurchefaunt and Ysayle aren’t there (because they are alive in this timeline) Estinien dies to stop Nidhogg. But then the minstrel is like “oh but WHAT IF” one more time, and you go back to the Thordan fight where he begs for his life. This time you spare him, and Thordan mocks your weakness and flees, but leaves behind his sword Ascalon, which you may recall has one of the Nidhogg eyes embedded in it. You take the sword and have the Nidhogg & Hraesvalgr fight again. This time you use the power of the eye in Ascalon to free Estinien from Nidhogg’s clutches. BUT WAIT ITS NOT OVER. Now Thordan swoops back in and steal Nidhogg’s two eyes and Hraesvalgr’s two eyes and becomes DRAGON KING THORDAN for the final fight. You defeat him eventually, your friends (Haurchefaunt, Ysayle, Estinien) are saved, but with Hraesvalgr and most of the dragons dead, it appears the Dragonsong war is destined to continue. What a mindfuck.
