Svartalfheim

Like all realms in Nidavellir, Svartalfheim was a system of underground caverns. Unlike the rest of the layer, however, the realm's stone walls emitted a silvery glow, while natural springs and geysers warmed up the rivers and kept the caves at a comfortable warm temperature. The entire realm emanated a feeling of peace and love. The realm had wild regions covered in dark forests that thrived on the earth's warmth and required no sunlight. Some of the caverns displayed abundant deposits of quartz, mica, and pyrite, of which the dark elves were overly fond and employed them abundantly as decoration and jewellery. The materials that made up the cavern walls had excellent acoustic properties. Throughout the realm, sounds were richer and sweeter, so that even the echoing sound of distant miners could be mistaken for song. This trait greatly improved the magical abilities of bards and amplified the singing abilities of even the most untalented visitors. It was common for people to continue to sing even after leaving Svartalfheim, unaware that this enhancement faded as soon as they left.
