Rings of Holnen
Ancient and Alien
Steer clear of the Rings. They say that dangerous cultists gather there on occasion. Followers of a strange God who's very name can shatter a spine.
The Rings of Holden are a world wonder in East Holnen, Aussel. Their origins are unclear, but what is known is that the rings have been there for thousands of years. The first known document that mentions the site originates from roughly a few decades after the arrival of the elchen in Lethea at around 2900 BA.
Time travel/space adventures/cosmic experiences/planar mishaps, here we go! Love the concept, it makes it so easy to theorize, whether it's the audience or the characters themselves
