If you are given the choice to live in eorzea

[AnimaAnimus]

First thing I would do is move to Ul'dah, be sure to join the Scions so I get to cover myself in some good thick plot armor and then go run around and do whatever I want, as my plot armor will protect me from death, maiming, imprisonment or any disease, curse or hex.

Then I would pitch both Alphi and Graha off the cliffs of the Invisible City, tell Ishtola to get &%#$*^@, go back to Elpis and tell the Convocation everything Venat and Hermes are about to do so they can deal with them and pluck Meteon before they do it and then, if our world still exists due to timeline splits, marry into the Hildebrand fortune so I can start a lalafell/sylph mulch mix service for the new Island Sanctuary. Bank and live happily ever after.

If the world then doesn't exist, well I will still be a member of the convocation and have a pretty sweet life as an Ascian so win/win
