Though the room contains experts about all things magical, scientific, and alien, not to mention Wenwu’s kin, none of them know the precise nature of the Ten Rings. What is clear is that they are incredibly ancient, and also that usage of them has activated a beacon. Exactly who or what is being called isn’t clear, and Captain Marvel and Banner have to cut the conversation short to handle other business (the former tells Shang-Chi & Co. that the latter has her number, but he denies this claim, and instead signs off, essentially welcoming them into the Avengers fold).
The mystery of the Ten Rings’ beacon is left open-ended, teasing Marvel fans with a cliffhanger question that we will hopefully see addressed sooner rather than later – either in one of the many upcoming blockbusters on the schedule, or in one of the developing Disney+ originals.
