Scadrian System page, regarding Well of Ascension

[Honorless he/him]

The Scadrian system page https://coppermind.net/wiki/Scadrian_system claims that multiple individuals had held the power of the Well of Ascension before Rashek without any citations. Is this confirmed?

Did some digging on Arcanum and found this WoB, saying that Preservation's original intent was that someone would take up the power every time the Well filled, and this one, which says there weren't a lot of Heroes (but implying at least a few) other than the ones we saw in the books; I've added those two WoBs to the page.

I feel like there's something that states it more explicitly than that, but I'm not coming up with a good Arcanum search that will get WoBs about the in-world Well of Ascension and Hero of Ages but not include a bunch of information about the books. My general sense of the timeline was also that Ruin was imprisoned for more than two cycles and I thought there was a WoB saying that the Well generated a bead of lerasium ever time it refilled, but I'm not finding anything that actually pins those down

I do believe there is some WoB, I believe one that I got, that does imply this, but I do not have time in the next while to go diving.

I have looked through every Chaos Wob and haven't found it. I'll try and look for it more another time.

I think the first WoB Stargazer linked is indeed the one I was thinking of, though it doesn't directly say how many. But together it does imply multiple.
