Trobriand's Graveyard

Trobriand's Graveyard is an area of Undermountain used as a scrap heap by the mage Trobriand. Each time he needs to dispose of a failed creation, Trobriand uses his wand of rejecting to send it to the graveyard. He assumed that everything sent there was inactive, but later discovered that this was not the case, and became fascinated with the interactions between his failed creations. He then set about supplying the mechanical inhabitants of the graveyard with what they needed, and experimenting with their reactions.

The name "Trobriand's Graveyard" was coined by Halaster, Trobriand's ex-master, after he showed it to him. As of 1368 DR, it is led by a scaladar known as Squch and populated with ten silversanns, twelve thanatars and up to thirty ferragans, as well as many more generic mechanical creatures.

Entrance
The entrance to the graveyard is a gate that appears like a will-o'-wisp. It travels Faerûn autonomously, although it is more likely to appear in areas where there has been recent heavy magic use or where there are large collections of magical items. It can be confused by an anti-magic shell or magic with a similar effect, and can be evaded by plane-shifting. Otherwise, the gate will attempt to teleport people into the graveyard (without their consent or knowledge) so that Trobriand can study their interactions with its inhabitants.
