Lorien (Babylon 5)

From Multiversal Omnipedia

Lorien was the first being in the entire galaxy to ever achieve sentience. He was the first and last of his race. He and his kind discovered the Vorlons and the Shadows when they were infant races and helped them along.

Lorien spent many millenia on Z'ha'dum waiting for someone to talk to, someone to guide, and caught John Sheridan when he leapt to his death. He taught Sheridan to embrace death, and breathed on the remaining embers to give Sheridan an extra twenty years of life. They returned to Babylon 5 where Lorien helped guide the Army of Light, and later helped to end the Shadow War, before going beyond the Rim with them.

Lorien briefly returned twenty years later, and took Sheridan beyond the Rim.
