Quote from AliasBot »Just gonna point out this passage:
The golden flash of light isn't actually consistent with the described effect of Bolas planeswalking in the Hour of Devastation story (there, it was described almost like a black void being ripped in reality), but this definitely has the feel of a really big planeswalker appearing in the sky and then descending to earth. And in a story where Bolas is described as "the Second Sun"...well, it would fit.Quote fromA flash of golden light flared like the sun rising at zenith, but the brightness was extinguished as quickly as it had appeared, leaving the stars again to shine. Yet some of those stars vanished in a descending trail, blotted out and then reappearing in a trail as if a large shape was falling out of the heavens. Naiva rubbed her eyes, thinking the storm had injured her vision, but when she looked again all the stars shone steadily. The clouds began clearing off as the rain ceased. Surely the falling blot had been nothing more than a distortion of wind and churning cloud.
Why Bolas would take the time to tell his side of the story with someone else's voice, I don't know, but that definitely felt like what was going on to me.
I had simply taken it to be Atarka. She does sneak up on them (How exactly does a massive dragon with glowing antlers "sneak" up on anyone/thing?) in short order afterwards.
