Loridas

Loridas was the last remaining elder on Lorien.

An Aeternus, like Ella, he was able to switch between times and his age, which was how he survived the longest. Later though when the Mogadorians invaded Lorien, he sacrificed himself so that Ella could escape with his powers, and become Number Ten.

They escaped though on a second ship.

He does not appear but is mentioned in The Power of Six by Crayton to Marina and Number Six about his history. Loridas makes his first but very brief appearance in The Last Days Of Lorien. He is seen by Sandor, Nine's Cêpan, and is revealed to be the one who put the charm on the Garde before they left Earth. He does not speak in this story, but provides a very important part that will help the Garde for dark future ahead of them.
