Aeten II was a planet located in Wild Space, on the borders of the Outer Rim Territories. The planet was known primarily for its stygium crystals, which could be used to create cloaking devices or as lightsaber crystals which gave a Jedi increased stealth and dexterity. The planet was destroyed in the first war, shortly following the Battle of Filo Coruscant, by Imperial Grand Moff Martio Batch, using the Tarkin superweapon.
