Babylon 5/Recap/S02/E16 In the Shadow of Z'ha'dum

In the Shadow of Z'Ha'Dum
"There are beings in the universe billions of years older than either of our races. Once, long ago, they walked among the stars like giants, vast, timeless. Taught the younger races, explored beyond the rim, created great empires, but to all things, there is an end. Slowly, over a million years, the First Ones went away. Some passed beyond the stars never to return. Some simply disappeared."

- Delenn
