i thought it was underground
yes
the glass eyeball is out the door that you break the chain off of
Cross the Library to the left and you should find a Glass Eye on the floor near the left bookcase.
Get down from the last chandelier and use the crowbar on the chained door. This'll provide an easy exit for when you need to exit. Go to the left and you'll notice a glass eye next to one of the armors. Pick it up. http://blog.poptropicahelp.net/island-help/vampires-curse-island/vampires-curse-guide has all the answers!!!!
You have to light the chandeliers first then you will find it at the left side of the library on the floor.
After you light all of the chandelers find a glass eyeball by a bookcase and put it in the lions eye and its mouth will open and the key will be inside.
I Have Completed That Island So I Actually Know It, You Have To Finish Lighting The Candles And There's A Small Part I Forgot So Yea Then You Will Find A Glass Eyeball Near The Left Bookshelf's Right Bottom Corner Than Place It In The Tiger Head On The Wall Above The Bookshelf Then It Will Reveal The Key For The Main Entrance But I Don't Want To Spoil The Time For You And Mostly Thats Only What I Remember Hope This Helps
like that but its smaller in the room
you have to pick up the glass eyeball and put it on the tiger then a key will come out of it's mouth and you can open the locked door.
Ok so there are two suits of armour right? Next to the one on the left side of the room (where the locked door is) is where the glass eye is. After you insert it into the TIGER not the lion it opens its mouth and gives you a key to the armour room after that don't ask me about the rest because I don't know anything about that I am quite stuck myself. . . LOL
When you have lit the fire and all the chandeliers, there will be a glass eye on the floor. Put it back in the tiger head to get a key.
Above one of the bookshelves is a lion and the lion has only one eye. Put the glass eye on the lion and the key will come out of the lion's mouth.
