Quick answer: The quest starts in a scene at the first Crimson Forest Crane Bell. Her illusion waits past the Gilded Lotus rock, at the stone lamp on the cliff edge, about 35 m from the Parting Mists bell.
Where to find the illusion of Inanis
Her illusion stands near the Parting Mists bell, about 35 m away, on the cliff above it. The scene does not start until you reach the right spot.
After you finish talking with her, keep moving along the edge. A short scene plays as she clears the mist. Past that point, a ledge drops down to the Parting Mists bell.
When the lamp scene begins, Inanis explains the Realm of Mirage to Soul and asks him to rescue the Chord. That exchange confirms you’ve reached the correct spot; once it ends, her dialogue menu appears.
What Inanis offers at the stone lamp
One of its options is “Train Abilities.” Pick it to work on Soul’s abilities with her before you continue along the cliff edge toward the mist and the drop to the Parting Mists bell.
