So it can depower the Ascended with moon beams, but can it repower them with the sun beams?
Is there a counter weapon that is used to power mortals to become Ascended?
I'm a little curious about the Chalicar's nature. It seems to be as much of a divine implement as the Sun Disc itself, though, as far as we've seen, the Chalicar might be moon-oriented more than sun-oriented.
Though, it could also be both, but, I doubt it could be used to perform an Ascension ritual. Hopefully we'll get more information about it in the future.
Why did they make it the key for the tomb in Azir's ressuraction story?
Well, it's mentioned that the Chalicar was "brought from beyond the mountain and raised aloft at Shurima's birth", so it's likely a symbol of pride and nobility held by emperors and empresses. The Tomb of the Emprerors could have housed the body of Setaka alongside other rulers, past and future.
Additionally, Setaka and Azir could have been close to one another in some way, shape, or form, so, if the Tomb of the Emperors was unique to Azir, it'd make sense for him to have her crossblade be the key to opening it.
This is all supposition, of course, but still interesting to humor.
Also, we have a possible new wielder of it, instead of Sivir:
"It is the blade that will one day be borne by Sivunas Alahair, the Bringer of Rains. In their hands it will be a weapon of great destruction, or a symbol of unity.”
This is where I throw out a theory that needs to be taken with a mountain of salt, but:
Perhaps Sivunas Alahair is Sivir's full name? Much like the curious, peerless, egg-eating warrior Saijax Cail-Rynx Kohari Icath'un in the story Where Icathia Once Stood is hinted to be our local peerless, lamp-wielding, egg-eating warrior Jax, it'd make sense for the mention of the Chalicar's future-wielder being named "Sivunas Alahair" actually being Nasus' prophesying the mercenary Sivir.
As for the title "Bringer of Rains", it could refer to Sivir's opening the Tomb of the Emperors bringing about the second age of Shurima, where life can flourish in the gods-forsaken sands once again.
While the gender (and identity in general) of this Sivunas character is left ambiguous, I wouldn't put it past Graham to leave a clever nod to our Champions in his stories.
But, again, take all of that with a mountain of salt.
