Okay stop me if I’m wrong but wasn’t Merrill actually right about the Eluvian?
She wanted to restore it because she belonged it was an important part of their culture and thought it could help her clan
But they thought it was evil and the keeper let her leave because of it.
But if she had been able to restore it, it would have led her to the Eluvian crossroads.

The place created by the ancients. The place to travel everywhere.
And Merrill was right about it.
