Hmm.... this may be an odd question to ask, but how much time would you guys think has passed since the creation of the Hain?

I need this information to help create my next post.

Undeniably hundreds of thousands of years. Possibly millions.

The Hain were made before a lot of these landforms, so I'm not sure whether it makes more sense to have them stay stagnant as a species for an incredibly long period of time or to just have all this shaping of the land done abnormally fast.

I lean towards the latter, because the White Sea being formed from an explosion would have been quick and that was the main event it seems.
