Beyond The Center (OSR setting)

So, everything I've put so far about this world has been in the center continent, which is probably the most inhabitable. I've been turning over some ideas for the other landmasses. 

1. The Westernisles: Three large islands to the west of the Northmen's territory. The largest seems idyllic, though it is covered in ruins from what seems to have been a once-great kingdom. Haunted by the Six Storms, which recur periodically over the course of each year and range from meteor showers to Fae hunts. The other two largest isles are Maberon, island of the Fae, and Ascapart, where giants rule over humans. 

2. Garganton: A massive continent to the west, a borderline death world where some magic causes its resident beasts to grow to massive sizes, with an average human only being about the size of a mouse or insect amidst the oversized wildlife. 

3. The Corpselands of Theann: A continent to the east, the original birthplace of humans, elves, and dwarves, and the site of the first civilization, which now lies fragmented and ruined amidst its own magical war machines, massive swathes turned to wasteland by ancient weapons. 

4. Half-Yozin: A continent connected with Theann that once warred endlessly with its ruling empire. The final battle between the alliance of Yozin and the empire ripped the coasts of the continent apart, and it is now a series of floating subcontinents and archipelagos rather than a single landmass. 

5. Drundiria: An island chain ending in a continent-sized landmass connected to the south pole. It's biomes seem to have been assembled without rhyme or reason, with icy peaks next to tropical beaches, and even stranger wildlife. Some say it was a sort of divine testing ground, while others claim that it periodically slides in and out of existence on the material plane, floating through distant worlds and universes before returning, bearing an accumulation of alien mysteries.
