You wake up in a bedroom to find a gash on your face and no memories in your head. Oh, you can talk just fine, and you remember some basic facts, but you have no idea who you are and why you are in a very gloomy and unstable old castle. After rummaging around and finding an old diary whose entries have all been torn out, you set out into the depths of the building, trying to find the scattered entries - because you're pretty sure you wrote them.
Due to some coding conflicts and the like, simply typing n or north (or the equivalent for any other direction) will generate an error response. You have to type "go" and then the direction if you want to move anywhere.
