Isildur gave us 3000 years of content
Including the Rings of Power
Oof. Well, the first season was good at least
Due to various reasons, he couldn’t. He really, really wanted to though.
Please correct me if I’m wrong. I was under the impression that according to official canon Isildur was traveling to seek Elrond’s council on what to do with the one ring when he was ambushed and killed and the ring lost.
Edit: I’ll correct myself, I was wrong. He was on his way to Rivendel, but not to consult with Elrond about the ring. He was going to pick up his wife who stayed there during the assault on Mordor.
They mean kicking him into mount doom when he yells at him in the movie. In the books Elrond was not at the fires with him, and only later did he know but it was too late.
