Well surely nothing bad could come of this, right? With one more deep breath, you reach a mostly-steady hand into the unsettling darkness. The feel of nothing but cold stone is somehow almost worse. Just as you’re about to snatch your hand back to safety, your fingertips just barely brush against something!

You look back up to the portrait and are startled to find it returned to its original state. The only evidence of the damage of the devilish flames is a slight darkening around the eyes and mouth.
