Once Giselle left Lex, and the Inn, her expression turned extremely solemn. Lex had managed to get a Defiler core, as per his needs, but she had gathered Defiler Essence, which was equivalent to the more refined bloodline of a human.
She would now baptize her body in that essence, slowly building up a resistance to the effects of their unique brand of Profane energy. Although it seemed like she was immune even now, that was a misconception. She was not even resistant to stronger Defilers, let alone immune, which is why she constantly had to enhance her body's resistance to Profane energy.
That did not require her to be in any specific place, so she hurried back to the Champions tourney, and did a quick search for Marlo and Lex's friends. As it turned out, they were all together.
