The "Cliff Fort Under the Clouds", Machike'Shikumo is both a fortified town (dating back to the Dark Elf exodus from the surface at the end of the Moons Age) and a surface colony on the rim of the Nidavellir.
The underworld city which Rosof once ruled is located beneath the ancient fortress known as Fustin'darun, which has recently been recoved and occupied by the Sarghress Highland Raiders for use as an outpost on the way to the surface. Machike is further protected by an eternal thick mist, which may or may not offer some clue as to why it was abandoned. Through deals made between Rosof and Quain'tana centuries ago, the Sarghress control this city and use it as a base of operations for surface campaigns.
Fustin'darun, the colony itself, is situated directly above the city and on the edge of the Nidavellir. It is walled in all sides, and has a large elevator reaching down into the mists of the underworld to ferry troops, supplies and travellers. Outside the wall lies the Emberi village where freed goblins make a living farming for the colony.
Fustin'darun is the colony located in the proximity of Machike'Shikumo and currently used as a Highland Raider outpost, as well as a growing colony for the clan's Drow and Emberi citizens--and recently, members from other clans. Notably among them are members of the Vel'Sharen, Val'Sullisin'rune, Val'Dutan'vir, and even the Tei'kaliath.
It should be noted that people have a tendancy to refer to both the town itself and the fort as Machike'Shikumo, despite the fact that it is the name of the town only. Whether this is because of the proximity, awareness of Fustin'darun is not that great or simply to avoid suspicion in planning a relic hunt (since the fortress is a military occupied structure) is unknown.
