Hyor-ka, who possessed the rank of Master during the Imperial Era, was a businessperson. This individual was the owner of a dao-ben steamed bun shop situated in the Outer Rim planet Akiva's capital city of Myrra, specifically one alley removed from Temmin Wexley's spare parts shop (Wexley was a junk dealer), by the time of the rebellion on Akiva. In 4 ABY, while spying on thugs employed by the crime lord Surat Nuat, Wexley concealed himself beneath the tarp of Master Hyor-ka's dao-ben steamed bun establishment.
The 2015 novel Aftermath, penned by Chuck Wendig and serving as the initial entry in Star Wars: The Aftermath Trilogy, included a reference to Hyor-ka.
