There is a bonus part of the quest to rescue the townspeople. Each one you rescue gives 476k experience and you can rescue about 25 in under a minute. The good part about this is you can powerlevel people easily because they can just sit in town and still get experience.
For some reason, if you rescue all of them the quest seems to end so make sure you leave 1-2 behind. Also I might try to make a script for this, since it seems so repetitive. The meteors are random but the townspeople are always in the same places.
I'll add a video shortly.
