Oh man. I imagine it would feel, like surfacing from the water after nearly drowning. It's shock, relief, confusion, all at once. All of her expectations for what the world could be like were completely blown away.

The 8th umbral calamity not only halted the aether of those it touched, it ruined the natural aetherical flow of the enviorments. Wildlife grew to monsterous proportions, unexpected and diverged from a natural course. Plants turned toxic, weather shifted, longstanding cities turned to ruin. Much like how Coerthas used to be hills then became stuck in endless snow, that was most of the world in one way or another. It's not that the world ceased to be, moreso that it became unregonizable as it's entire soul shifted drastically into something else, Terraforming into a new thing all together slowly.

When she first lands in the current timeline its in the Dravanian hinterlands, and it takes her a second after she stumbles,to catch her breath. Green fields, a clear sky, fresh water. Life flourished all around her, she had known it would, but the sight of it woul'dve hit her like a truck. But, being who she is, I think the awe would turn bittersweet. I don't think she wouldve expected to feel resentment towards it, but she would. In her eyes she is witnessing something that she feels was taken from her and her timeline, it would be hard to ignore that aspect of it I imagine. Any expectations she did hold were definitely blown away, she just has complicated feelings about it
