From Medivia Online Wiki
Near City: Icenhaal
Location: Deep below Forgula
Gerenal Info: One of the Forgula's Tombs, located deep under the surface. Tomb is occupied by undead creatures, especially different types of skeletons. Most of them might be dangerous for unskilled players so be careful during exploration.
1) In the tomb you will find 1 Ancient Bone needed in one of The Lightbringer Faction Spoiler mission.
2) Goshnir, a powerful Necromancer rarely haunts the Skeleton Tomb. Killing him is one of The Lightbringer Faction Spoiler mission.
3) The tomb is probably the best place to complete tasks from The Lightbringer Faction Spoiler, like Skeleton Archers, Skeleton Sharpshooters, Skeleton Plaguespreaders, Restless Skeletons and Skull Reapers.
