Look for other rooms
From Create Your Own Story
You decide to check for other rooms. A few doors down, you find another unlocked door. It leads to a parapet. The afternoon sunlight nearly blinds you after the darkness of the castle. A stiff breeze tugs at your clothing. The door clangs shut behind you. You turn and pull at it, but you're locked out.
With no other path available, you follow the parapet around. Eventually, you come to a stair. It leads down into a shaded courtyard. One of the walls of the courtyard is knocked over, giving you access to outside.
You make for the break in the wall.
"Goink somevhere?" You turn to see Walfreid standing in the shadows behind you.
