Krylon
Krylon is an existing planet from Legends.[1]
The planet's atmosphere was so toxic that Humans had to wear rebreathers outside. There was a repurposed Kooroo shrine beneath a monorail bridge on the outskirts of the planet's capital that functioned as a meeting place for members of the Church of the Dark Side. Near the shrine, just outside the city, was a junkyard which was owned by Master Kilv in 5 ABY and employed a crane operator named Buller and an unidentified Besalisk worker. In the vicinity of the spaceport, there was a domed plaza in a mixed-use area where a starship rental agency was located.
In 5 ABY, the false Supreme Prophet Kadann and Triclops escaped from Yavin IV in a makeshift spacecraft and made their way to Krylon by sublight speed. They sold the spacecraft for scrap at the junkyard and then convinced a number of local devotees of the Church of the Dark Side to pool their funds and buy a ship for them. A short while later, Ken and Mammon Hoole, in the guise of Tash Arranda, tracked Kadann and Triclops to Krylon and acquired a tracking fob for the ship they had bought.[2]
