2nd Battle of Weye

The Showdown at Weye, also known as the Second Battle of Weye, was a battle that took place after Morgoth Bauglir consumed the Heart of Molag Bal, becoming a Daedric Prince. However, it didn't kill Molag Bal. As punishment, Bal raised all of his forces to go after Morgoth,

The Battle
Jyggalag rallied his forces of Order near the artifical sun, where he was at. He resurrected Laza after his duel with Gothmog and Deathbringer Volar. Morgoth went west, riding his dragon Glaurung to the battlefield of Weye. When he arrived. he managed to create a crater using Grond, killing soldiers of Molag Bal and Order alike. He then summoned all of his generals to fight for him, raising the undead along the way. Molag Bal summoned Menta-Na, the flying Daedroth to go after Morgoth's dragon Glaurung. They clashed for 1 day with no one winning.

A day later, Mairon, Morgoth's right hand man, transformed into his master to distract Menta-Na, which allowed Glaurung to mortally wound the daedroth.

While the fighting was going on, Morgoth, Ungoliant and Carcharoth went inside the cocoon of order, killing many soldiers of Molag Bal and Jyggalag along the way.

Jyggalag marches out.
Jyggalag was interested in Morgoth so he went outside the Throne of Order. He managed to encounter him and they fought. Jyggalag was then struck by a web of pure darkness by Ungoliant, leaving him immobile for a few hours.

The Throne of Order
Molag Bal found a secret entrance into the cocoon, reaching the Throne of Order before Morgoth did. There he summoned his servants like Vernaccus, Orthe, Kathutet and Volar to his location.

Then Morgoth appeared and hell broke loose, both parties were attacking each other with such aggression that the realm could fall apart. Morgoth realised that he couldn't win against Molag Bal so he teleported himself and his servants away but Molag Bal used black magic to push Morgoth into the floor and nearly kill him. Morgoth was saved by Glaurung who took him away to safety. However that didn't last though as the followers of Molag Bal chased after him, cornering him at Mathmalatu Priory. This is the beginning of the Retreat from Coldharbour.
