Elena's original plan was simple, at least in its first stage.
The first step was to monopolize the treasures of the Holy Light Realm. Of course, the real meat of the plan came after this step ended, but it was essential for the days ahead to take hold of every treasure he possibly could.
However, Damien now had a secondary goal: to use this secret realm as a stage for Xue'er, and if possible, initiate her Baptism under the eyes of all those experts outside.
Xue'er needed to make a proper wave upon her introduction, or she wouldn't be taken seriously at all. The current Xue'er was naive and easily exploitable, something unacceptable if she wanted to survive without his umbrella shielding her from the rain.
