Shawken Device

The Shawkenese universe destroyer was the most powerful superweapon ever developed. Located on the planet Shawken, it was built by an unknown Shawken scientist countless years before the Battle of Endor.

This scientist was a nihilist who believed there was no purpose to anything, and that the only way to generate a purpose would be to destroy the universe and cause a new Big Bang, thus creating a new universe.

The Shawkenese universe destroyer functioned thusly: it would destroy the planet of Shawken itself, and then send the fragments through hyperspace to collide with other planets. These planets would explode and continue the cycle, until all matter had been destroyed and the universe ended from heat death and, presumably, birthed a new one.

The scientist died before setting off his weapon, and over time the Shawkenese buried it underground and tried to forget about it. Rik Duel and his gang accidentally triggered this device in 4 ABY, but it was successfully deactivated by Luke Skywalker and Kiro.
