MSQ: A thought regarding dragons' eyes

Vrtra gave an eye to Azdaja to save her, but what about her own? We retrieved one from Cagnazzo but I don't think the other one has been accounted for. Zeromus would have drained the aether from it, but the actual eyes seem remarkably sturdy in other cases like tracing Nidhogg's eyes through to Shinryu to still being intact when Estinien finds them afterwards.

Also, I wonder if we get Auri from Azdaja to match Varshahn at some point?

I don't really get why his vessel is out of commission, either. He removed his power from it to give it to Azdaja, but he still has his other eye to plug back in later, same as he does with the child form.
