get out of the tower

"All you have to do is inject your mana into this relic it will open a portal that will lead us to the exit." She took out a small stone that gave off strange energy and gave it to Alvine who looked at her with absent air.

"Don't stare at me like that, I'm the guardian of the key and I can't use it to open the gate, if you killed me to have it, you will be recognized as the new guardian and you will find yourself in the same condition as me. But if I had given you the key, not only could I not escape with you, but I would die under the effects of the curses of the tower. Do you now understand why it was the only solution for both of us to get out of here?" Seeing Alvine staring at him with annoyance, she could not help explaining to this guy who even distrusts his existence.
