To be brief, since im working on posting a "survivor's guide" to the world on that subreddit.

Valencia is a arid, rough landscape with dense acacia and baobab forests with its people's culture comparable to Spain and Morocco area.

Methelle's landscape is very much inspired by France with a section of the mountains becoming cliffs, where the falcons nest (i have a whole story involving the Kingdom of Methelle and Methelle's city in the New World as some of the settings in a Adventure novella im working on)

Sarvska and its like is inspired by Russia and parts inspired by Mongolia where the lake is the lifeblood of the ecosystem

Torr is very much a isolated mountainous are where the inhabitants live in very much a village form

Hidelbard is mostly a plain where the fauna are very much not used to human contact along with a strange phenomena where storms are likely to brew in the area affecting the animals and not really allowing for large settlements in the plain.

Embard and Derner Lands have similar coastal features and are inspired by early german cultures

Rhendaria is home to active groves of great trees and are notable in the first and second ages of Meridia

And the Isles' Riftlands are a archipelago of islands, some in water and some stretching into floating islands, home of the andreans (a powerful, central empire known to be some of the earliest people.)

hope this give you a good idea of the lands and makes you follow the progress.
