I can't live while hiding. It's impossible to keep my powers under control every second of the day. If the High Priest notices that they change according to his proximity, I won't be able to pretend not to know anything.
Then, I realise. He's close enough to feel it already. It's late to hide now.
I can just pretend I have no clue about my powers and pretend to be finding out now. Whatever happens, later will be taken care of.
I might even pretend to have the aura but not any powers. People like this do exist, just like some mages don't have any aura.
As the High Priest walks in, I can feel his aura so close. My powers can't be hidden all of a sudden. If I can sense him, he can do the same.
I sigh and get comfortable in my seat. I better play the best show of my life.
