Get into the castle


Entry is via the front door, which is locked and guarded.  The key is on the bottom of the lake in the South-West corner of the grounds, and is difficult to see. One way to find it is to dive down and locate the body, then swim over it from between the feet up to and past the head;  a little further on is a Water Crystal - turn 90 degrees left, and the key will be just in front of you.

Make your way towards the front entrance and extinguish the torches from a safe distance. Crouch, and creep towards the door - if you are careful you can get near enough to unlock it without being seen. Now run straight through the door, then through any one of the other three doors and hide in a corner until things quieten down.
