"Arcenstone" is a dungeon synth song by Summoning, from the EP "Lost Tales" released in 2003. It was originally written for the darkwave project of Silenius called "Mirkwood", which was never released.
Here Thorin, lay your Arcenstone, upon your breast
and let it lay there until the moutain falls
and may it bring good fortune to all your folk that dwell here after
