How much do we know about what Satella actually did? [discussion]

Satella destroyed the world, rampaging around for a long period of time, turning entire places into ash, until she was sealed away. That's why she's hated. That's why silver haired elves with purple eyes are so feared.

And I gotta ask, I'm not very deep into the LN, but are there any records of what she destroyed, or the things she targeted? For instance, are there any mentions if she just wiped out half the world as a whole (etc, wiped out the equivalents of carthage and rome), or did she just cause rampant, but more spread out destruction (similar to the massive plagues that massively weakened the roman empire).
