Some months before Rubick became Grand Magus, he had claimed an immense patch of land known to many as Jarcanis Hollow. This great stretch of uneven ground was strewn with thin, dark trees and murky marshes. In a place that no thinking creature would normally find interest in, Rubick had discovered something unique. There were clear signs that this had once been a place of many great magical altercations and duels, likely long since settled. Many of the trees were now withered husks with large chunks taken out of them. There were signs of old scorch marks and lightning strikes. Rubick took a great interest in this place and its apparent history with the arcane. He investigated the significance of these battle scars upon the land and began to practice the types of spells that could do such damage. As soon as he cast his first spell in this gloomy forest, he felt something peculiar underneath him. A mighty power. He traced the source of this energy to a great many scattered channels of bright green slime flowing throughout the grounds of Jarcanis. Rubick found he could take advantage of these fluxing, gushing streams of pure, arcane sap. Much like the timeworn, ashy trees around him had used this power to live on for ages, whoever practiced magic in this forest could tap into the ancient energy below. It was here that Rubick spent a great deal of time with his powerful trade, as the Slime Lord, using the great energies of the land to make himself stronger, more malleable, and much grander.
