A cottage in a clearing

Bianca had long since known about the transformative properties of the tower, but knowing and seeing it are far different. Walls slowly change from dark stone to empty spaces, with trees and bushes covering any line of sight. Slowly, as she walks further and further, the room turns into a vast forest… and just as quickly, she reaches a clearing in the forest. A small, cozy cabin lies in the center, smoke puffing out of its chimney, making for an oddly peaceful scene, contrary to what Bianca expected.

After surveying for a few minutes, Bianca finally decides her only way to continue is to head in and see what her first target was.

She slowly walks up, and immediately her first question is apparent: does she use the front door? Or head in through the back?
