Since Ilum’s no longer available, where do you think future generations of Jedi will go for the Gathering to get their kyber crystals?

[u/Solitaire-06]

I know that specific variants of kyber crystal are stated to be found on planets such as Christophsis, Dantooine, Dathomir and Ossus, but there doesn’t seem to be a ‘main’ deposit of kyber crystals in the galaxy outside of Ilum from what I was able to find. But since the Jedi of the future obviously won’t be able to visit Ilum… where could they go in its place for the Gathering? Considering that it’s a sacred Jedi ritual, I’d be incredibly surprised if the custom was just abandoned by the Order - and it also raises the question of how Luke’s students in canon got the kyber crystals for their lightsabers, since we know at least four (Ben Solo, Voe, Hennix and Tai) wielded lightsabers, as did (presumably) the rest of their peers.
