How to complete Freyja's quest in Elden Ring: Shadow of the Erdtree

The Elden Ring Freyja quest in Shadow of the Erdtree is one of the shorter stories in the expansion but it could be more straightforward. Depending on how you explore the realm of shadow, it's easy to miss a step and lose track of this warrior entirely. Ahem.

Freyja's storyline is made more tricky in that she stays put for quite a while and then moves when a specific event happens. Of course, if you're not aware of the significance of that event, it's easy to rush ahead and mess up the quest.
