The Recapy context you gave (metadata-level summary) doesn’t say what the ancient power actually is. I don’t have the film’s plot details in the provided context, so I can’t state it definitively from that material.
If you want to proceed, pick one:
- Upload or paste the scene/summary that names or describes the power, and I’ll extract the answer exactly from that text.
- Want a short, clearly labeled speculation based on the wider Avatar canon (may differ from the movie)? I can list plausible candidates and what they’d mean for Aang and the story.
If you want speculation, here are a few likely possibilities (related-canon guesses, not claims about the movie):
- Energybending: the rare ability to remove or restore bending and manipulate spiritual energy (as in the original series).
- Spirit-world power/portal: an artifact or technique that lets humans permanently bridge or control the Spirit World.
- An Air Nomad/artifact technique: a lost Airbender practice or relic that could revive Air Nomad culture or grant mass spiritual renewal.
- A lost Avatar/ancient-Raava-related power: something tied to the Avatar’s connection to Raava that alters or amplifies the Avatar State.
Tell me which option you prefer.
