Hy-Vinael is a vast, infinite expanse of pristine wilderness covered in lush forests, massive mountains, perfectly clear streams, placid lakes, and an expansive ocean called the Sea of Stars. The realm stretched from the boundless mass of the Sea of Stars to a range of snow-capped mountains.

The deep woods of Hy-Vinael possessed an unearthly beauty, enough to cause a profound since of comfort and wrongness in equal amounts, and many non-elven visitors can get overwhelmed by the liminal feeling this beauty causes. The realm is full of secrets and mysteries that were known only to the elven deities that tend to inhabit this plane.

The thick canopy of the forests was divided in layers in many locations: an upper layer of sun-loving trees and a lower layer of shade-favoring vegetation. In some of the thicker forest areas, the undergrowth was nearly impenetrable, due to a combination of dense foliage and the trunks of dead trees. Those areas were dangerous and generally avoided by even the native elven inhabitants. The darkness of the forests was offset by the brightness of the meadows in Hy-Vinael. They were characterized either by their perennial flowers or by the blue blossoms that grew above the snow during spring.
