===Craftworld Eldar===
The [[Eldar|Craftworld Eldar]] have some respect for life (and not nearly as many weapons of mass destruction as they had before the [[Fall of the Eldar|Fall]]) so they don't do it often. Didn't stop them from purging all life in the Octarius system to clean up [[Kryptman|Kryptman's]] mess, though (in that case the Dark Eldar provided the WMD). The most well-known Eldar engines of planetary destruction are called [[Blackstone Fortress|Blackstone Fortresses]], which are ancient weapons they designed to fight the [[C'tan]]. To put it simply, think of a floating citadel with a distort weapon (like the ones the [[Wraithguard]] have) the size of an Emperor-class battleship. During the Gothic Wars, three Blackstone Fortresses combined their power to cause a star to go supernova, destroying an entire solar system.

In Apocalypse War Zone: Valedor, the Craftworld Eldar from [[Iyanden]] procured another type of ancient WMD, the Fireheart: a complex nodal resonator capable of causing a planet's molten core to enter violent death throes and send lakes of lava to the surface (or just explode two-stage torpedo style, the tie-in novel plays the fireworks up to a big degree). The [[Dark Eldar]] originally had this, but they gave it away because they didn't have the psychic power to activate the weapon. The Fireheart was used successfully on Valedor and prevented Hive Fleets [[Hive Fleet Kraken|Kraken]] and [[Hive Fleet Behemoth|Behemoth]] from joining forces. If they had, the [[Tyranids]] would have had all of the genetic data of the Orks and the Eldar, enabling them to fashion unthinkable monstrosities.

Before the fall (and possibly still kicking around somewhere) they had devices that fired entire suns or black holes at their enemies.
