Last Alliance

At the destruction of Numenor, Sauron was believed to be dead. When he started his attacks against Elves and Faithful Numenoreans, they formed the Last Alliance.

They entered Mordor and a final battle was fought at the gates of the Dark Tower. High King Gil-galad, Elendil and his son Anarion were killed. In the end Isildur cut the One Ring from Sauron's finger and his spirit fled his body. Thus ended the Second Age.
