I dare you to try. : p

1. Shadowfall

Perhaps something to do with ascians, and the fall of an era?

2. Windrise

Thavnair?

3. Geopath

I was trying to think of one for the possible Hingashi expansion.

4. IreTome

Ireland + tomes knowledge? This would fit Old Sharlayan. Ire is also a word to describe fear.

5. MjolnirsMight

Unlikely to ever get an expansion, but Airselant looks cool.

6. Nethiright

Ivalice restoration expansion. With the theme of nethecite?

7. DragonSong

I know it sounds similar to an actual XIV song, but we do have Meracydia as a continent. Though I strongly feel like it would go with Thavnair as an xpac, it isn’t unreasonable to think it wouldn’t be its own thing too.
