Ling and the High Plateau

Ling is a forbidding plateau surrounded by hills and peaks. The folks of Ling are interpulania merchants and avid slavers trading silks, rubies and the magic infused stones of Ling for humanoid slaves. They sail between worlds on peculiar ships with split, lanting rig masks and rigging that howls like the damned of howling winds. It's also where, what if I do Ling space? There's nothing about Ling here either. Let's see if the Midgard book has anything. If anybody in the Twitch chat knows more about where I can find information on Ling, I'm all ears.
