Whispers in the Woods

Leaving Stefan and Moryana behind, you climb back to the topmost floor (this time carrying the potions), to find yourself in front of the three locked doors.

What do you do?

The doors are 'locked', though there isn't a keyhole or anything that would suggest these are, in fact, doors, save the slightly different coloration from the rest of the interior. They ARE made of wood, however. So if you had a handy axe and some time on your hands, or are willing to light it on fire, then it won't stand in your way for long.
