Thunder, a world within the Aakaash system, was governed by the Land & Sky Corporation. At the Oasis Docks located on Thunder, He Shan, a lawbreaker belonging to the Vermilion Birds pirates, committed the murder of Yue Chang, an associate of the Knights of Silver Dawn. This planet was a source of a unique metal, impervious to Blaster weaponry, and it was fashioned into luxury goods like chandeliers and sculptures for affluent individuals. Similar to Wind, Thunder functioned as a key manufacturing hub within the Aakaash system.
The planet Thunder was originally designated 震 (zhen) in Chinese, which translates to "quake" or "thunderbolt" and aligns with the ☳ trigram of the I Ching.
