Skytree is the oldest tree on Eternia and the only living thing on the planet older than Granamyr. In exchange for telling He-Man and Teela how to reverse a spell that had turned Man-At-Arms to crystal, the jealous dragon sent them to the Forgotten Forest to chop down Skytree so he could watch it burn in his fire pit. They made their way past Skytree's protector Tullamore and explained the situation to it. Skytree recalled that an old Man-At-Arms had saved the Forgotten Forest from the Witches of Fire, and agreed to repay its debt by sacrificing itself to save the current Man-At-Arms. He-Man and Teela, however, decided to spare Skytree, and received both its thanks and apologies for doing so.
