| Map | Hallveig Forest |
Hallveig is a towering forest situated to the west and south of the Sahânzar Valley. It is home to the world's sole source of Hyperion Blackwood. These majestic trees can reach heights of up to 500 feet, with the oldest specimens boasting bases that measure sixty feet in diameter and massive, gnarled limbs that often intertwine and anchor themselves to the surrounding trees, making the harvesting process exceptionally hazardous. The leaves of the Hyperion Blackwood emit a rich, musky aroma, which is used in the production of perfumes and soaps. However, this pleasant scent also serves a more sinister purpose, as it masks the odors of those who dwell within this forest.
Even with the expansive canopies, light still filters down to the forest floor. Owing to the translucent nature of the leaves, only the substantial limbs of the Hyperion Blackwood yield to shadows and darker regions.
Hallveig is home to colossal owls, colossal praying mantises, colossal bees, and other colossal creatures. It also harbors a variety of normal-sized animals and insects. Many fey dwell here, and similar to the N'nathil Forest to the west, it is a rugged region with no central governing body.
