Our heroes enter the broken tower, seeking an escape from the evil without.  

NGL, I learned a tough lesson with this part.  If you read for the audience in things like this, either map it out, or don't, but remember to keep your focus within the light of the torch.  That was my mistake.  You as the reader shouldn't see further or describe further than the furthest spot the heroes torch reaches to.  I'll work to amend this concept in the future.
