A starship launched missile; which once launched, would create a fiery blast of immense heat, and destroy almost everything in its path.
Destruction of RakisEdit
The Weapon were first used by Honored Matres in their major attack against Rakis, in their successful attempt to kill Supreme Bashar Miles Teg. Because Teg had killed some of the Matres’ leadership earlier in the year while on the planet Gammu, Teg, the Bene Gesserit Mother Superior Alma Mavis Taraza and the Tleilaxu Master Scytale knew that a retributive strike would come. With Sheeana, who gathered a sandworm from the surface of Dune, Taraza's assistant Darwi Odrade and Scytale fled the surface of Rakis, just before the Matres arrived. Teg stayed behind on Rakis to ensure the prior group’s escape.
When the Matres struck Dune with the heat-based devastating Weapon missiles, the atmosphere immediately caught fire, which caused half of it to evaporate. The immense fireballs scorched the surface of the planet killing almost all life on the world, sandworms and humans alike, including Teg. Much of the sand on the covering of the planet, when exposed to the extreme heat of the resulting explosions, fused into a type of hardened glass.
