The Ice Blades are a series of massive ridges of ice running mostly north to south in the southern part of Yuan. Not much is known about them, except that most consider the formation to be unnatural because of the evenness and regulatory of the “blades”.

There are monsters there, most notably the Ice Wyvern, but those that do are so adapted to the harsh cold they never venture far beyond the blades.

The Ice Blades are largely unexplored, somewhat because of the monsters but mostly because there’s virtually nothing there but ice. It’s also in such a remote part of the world that exploration simply isn’t considered worth the effort or risk.
