Irontree

Irontrees were a type of tree native to Mustafar, notably found within the forest of Corvax Fen. Many had been planted by the Alazmec of Winsit, in a vain attempt to replenish Mustafar's ecosystem. Most of the trees had died off due to the planet's harsh condition. By 35 ABY, when Supreme Leader Kylo Ren arrived on Mustafar to retrieve the Sith wayfinder which belonged to his grandfather Darth Vader, several irontrees were on his way to Fortress Vader as he fought against the Alazmec of Winsit.
