Babylon 5, Season 4: No Surrender, No Retreat

[Delenn and Sheridan "negotiate" an end to the Vorlon-Shadow War]

Delenn:
The others have rejected you! How do you have a war when no one will fight for either of you?

Sheridan:
We refuse to take sides in this anymore! And we refuse to let you turn us against one another! We know who we are now. We can find our own way between order and chaos!

Delenn:
You can kill us one by one, and those who follow us, and those who follow them, on and on, every race, every planet. Until there's no one left to kill. You will have failed as guardians. And you will be alone.

Sheridan:
It's over because we've decided it's over. Now get the hell out of our galaxy! Both of you!

[The Vorlons and Shadows hesitate, but Lorien steps in]

Lorien:
As I taught you and stepped aside, now you must do the same. Our age is past. This…belongs to the younger races now. They have learned to stand on their own. They have learned…to understand. Time to let them go.

Shadow:
Will you…come…with us?

Lorien:
I have been here since the beginning. I will not leave you now. I will go with you beyond the Rim, and we will see again all those who went ahead of us, all those who we have missed for so long.

Vorlon:
Then…we will not be alone?

Lorien:
No. Never alone.

[The Vorlons and Shadows disappear, and their respective fleets leave the system]

Marcus:
Did we just win?

Ivanova:
Don't jinx it.

[Lorien turns to address Sheridan and Delenn]

Lorien:
I waited a long time for someone to find me. Now, like the others, I find I hate to leave. But none of us can stay behind this time. That was why it was necessary to find all the remaining First Ones. This…is yours now. And you have an obligation…to do as we have done. To teach the races that will follow you and, when your time comes, as ours has, to step aside and allow them to grow into their own destiny. If your races survive, if you do not kill yourselves, I look forward to the day when your people join us…beyond the Rim.

[he starts dissolving into a ball of light]

Lorien:
We will wait for you…
