I'm on the second floor of the castle trying to get into the aunts bedroom but many of the doors are locked and thief/bust proof. In one bedroom in the southern area close to the library, a secret door shows up in the next room but I can't find a way to get to it. Help!

The bedroom is in the middle left of the 2nd floor. Nalia's aunt is in there, then in the back corner of the room a purple door should appear, just give it time.

When you find the room with the golems in it, be prepared for an attack if you take the items out of the coffins. Do it after clearing the basement and run like hell. The items are well worth the time spent.

You need the Keep Key from the room where you fight that Yuan-Ti creature who is guarding the stairs going up to the roof. That key will open the door where Nalia's Aunt is and from there, go via the secret passages to the stairs that lead down to the cellars.

On another note, those Golems will only attack you if you take any item BESIDES the last part to the Flail.

Syl...

Thanks, that stupid key that didn't look like a key was all I needed.
