If you do not write anything that your magi does then I will write something that you will have to react to.
Come the night, a lioness is found prowling into the infernal area to try to find the spirit and traces of it. What makes the lioness unusual is that there is like a blanket over her back that goes around the legs. It is a form of armor thanks to magic performed after her change so that she is ready.
Purifying flame will be going over anything infernal that she can find if she doesn't find the demon. Nose, ears and eyes are all on watch for the foe. The woman might not be the only infernalist and so she slinks along carefully.
At the dead of night a glowing apparition appears from the ground and hovers above the ruin. It awaits silently.
