Yes - Save her from herself

Your hand rushes inbetween hers, your fingers briefly entangling as you keep her from touching the ancient tome. "Don't!" Is all you get out, before you end up connecting with the book yourself. It's like a tidal wave of energy rushing over you. all you think, you touch, taste, smell, hear and feel - It is all power. Infinite and overwhelming, like a sun's fire swallowing you whole. You wish to scream, but your voice is gone. You wish to see anything but, yet your lids do not close. Color washes over you, reaching inside of you like caustic sour rain trying to wash away the beauty of the world.

You are stronger than this. You have seen dreadful creatures wash up from the deeps of the infernum and banished them, you have learned of things the average mortal will never conceive of in their nightmares. You will not lose yourself to a bad moment of chance.

When the book wants you to let go, to go limp and obedient, you instead ball up your fists, pushing this immensity away from you, coiling it up within the pages like crumpled paper and regaining hold over your body. You build up an impulsive arcane barrier against this power and when you come to yourself again, you find yourself on the floor, across from where Lana is now sitting, shock on her face, mingled with awe. The book is clutched to your chest, closed and sealed for the time being.

Lana stays there, eyes wide. "Are you...alright?"
Her voice is trembling. She is scared, clearly. She has, briefly, seen the energies coil around you, trying to eat away at you and you came out victorious. It must have been both imposing and impressive, to see one of your kind overcome such ancient powers. "I....am fine." You say, your voice already radiating some of its newfound command, sending pleasant shivers up the woman's spine.

You just sit there for a while, letting your magicks regenerate and the adrenaline die down. After some time, she raises her voice again, meekly, slowly shuffling a bit closer as if seeking your comfort. "You saved me." She realises in a heartbeat, "That book is bad news. I'm sorry, I got so excited and you always told me to look for...opportunity."

Who can blame her? You likely would have done the same. Then again, you are more capable in subduing such ancient strength, she is not. You might be able to teach her, if you'd like. Then again, there is always the option to cut that ambition short here and now. You still got a bit of energy left in you, if you want to take this power for a test run.
