Loki had contained the timelines, giving them life. But before he did, a Daughter of Artemis was born in one timeline, but she shouldn't exist.

Some unfamiliar people and a woman with silver eyes also appeared. The doors closed, and a hologram technology appeared in front of them. Once it opened, it said, "He Who Remains."
