Ignoring any leaks, there was bound to be something to do with Ahamkara and wishes the moment the last card in the Arcana deck was revealed to be "Wish". It is even in the Season Trailer. I had ideas about how the "Wish" might play into the Season's ending, but one thing I honestly didn't expect as a resolution was Eris Morn banishing Xivu Arath from her Throne World and giving up all her power as a result, leaving the Imbaru Engine up in the air. As for entering the Traveler, I have thought it could be tied to the Witness' ability "to move worlds from one reality to another". That such a power would be needed to safely traverse the portal from our reality to the Pale Heart. That said, the ongoing relevance of the Worms this year, and the near-guaranteed significance of the Ahamkara next season, makes me wonder if there are ties to how the Witness itself was able to enter the Pale Heart of the Traveler. One could assume the Witness just had the raw power necessary to make the journey on his own, but we did learn this Season that the bargain Eris made with Ahsa [url=https://www.youtube.com/watch?v=wNSp3pghyYU] is the same as one the Witness made with the Worm Gods eons ago[/url]. The Worm Gods and the Ahamkara share a common ability: feeding on the gradient between what is and what might be. If an Ahamkara Wish is indeed necessary to enter the Traveler, then the same could be said of the Worm Gods. The Witness might have sought out a bargain with the Worms to allow itself the means to pass through the portal when the time came. As far as the Ahamkara having a connection to the Traveler, it is possible they've followed the Traveler across the cosmos to feed upon the changes it makes to reality since terraforming dead and inhospitable worlds into verdant paradise with the Light fits the definition of changing reality with one's will. There is also [url=https://www.bungie.net/en/explore/detail/news/51148]The Hidden Dossier[/url] to consider. Ikora discusses the true nature of "Truth to Power", and it is one of the clearest contenders for what Savathun might have meant when she said she already showed us how to enter the portal. The Ahamkara are brought up there as well, with Ikora mentioning how they want to become "more real", and that the Anathematic Arc is a means for them to reach a place they consider "more real". If the Pale Heart does turn out to be a "parent universe" to the Destiny setting, then the means to reach it could be tied both to a power to move from one reality to another and to the Ahamkara and Worm Gods' ability to derive sustenance from what is and what might be.
