You are forbidden from going to Shadow Forest for a very good reason - no human who enters there returns alive.

If, however, your brother or sister or best friend goes missing in there, and you want to rescue them, then you will need to know certain things. You will need to know how to stay alive, and you will need to be aware of the sights you are likely to find there. And also, I recommend you take a copy of Professor Horatio Tanglewood's book, as it has details of all the deadly creatures you are likely to find and their fatal weaknesses.

Good luck!
(You're going to need it.)
