It had been nearly two whole months since Sargan activated the Spatial Energy within the Mystical Spiritual Connection Ring that Azaroth left for him and entered the Purgatory.
The Purgatory hadn't changed all that much since Sargan left it.
Sargan lived on the Frascoia Continent for nearly two years, and his body had gotten used to the environment there.
Thus, he felt somewhat uncomfortable as he returned to Purgatory.
Sargan was somewhat glad since he didn't need to be careful in using his techniques. On the Frascoia Continent, Sargan had created an illusion to prevent anyone from figuring out that he was utilizing Demonic Ardor instead of Humanely Ardor.
It was Azaroth who set up that illusion, while Sargan had to actively utilize his Demonic Ardor to maintain it.
Now that Sargan had returned to Purgatory, he could use his techniques to their full potential.
