Pause the Past, Save the Future

Pause the Past, Save the Future is a Versal quest started by Hera.

Part of The Versal storyline and A Plea from Versal: see every quest in order.

Requirements

Offer: (Every clock in Versalibrium has stopped at the same minute. Two girls in matching coats hurry up to you, hand in hand.)
I am Hera, and this is my sister, Mera. The Relic in your bag is humming, isn't it? It hums for us. We carry the same light as the Teardrops you have gathered. We are the last two.
The night the Antellion broke, time broke with it. Past and future crash into our town from the edges. The elders stopped every clock to survive, and my sister and I hold the rest still with our own light. Nobody here has grown up in a thousand years.
We want to give you our light. But if we leave our posts, Versalibrium will fall apart. Will you help us steady the town first?
In progress: Have you decided? Talk to me, Hera, when you are ready to help steady Versalibrium.
Completion: Thank you. Then we start with the past. It crashes in harder than the future, because it has more to say. Time runs like a river, Mera says, and the past is the deepest part.
Find the tower in the east, the one called Back to the Versal Past. It leads into the town as it was before the clocks stopped. Speak to me once more before you go in, and I will tell you what to do.
