“Look，” said Tirian and pointed. Not many yards away grey battlements rose above the tree.tops， and after a minute‘s more walking they came out in an open grassy space. A stream ran across it and on the far side of the stream stood a squat， square tower with very few and narrow windows and one heavy.looking door in the wall that faced them.
Tirian looked sharply this way and that to make sure that no enemies were in sight. Then he walked up to the tower and stood still for a moment fishing up his bunch of keys which he wore inside his hunting.dress on a narrow silver chain that went round his neck. It was a nice bunch of keys that he brought out， for two were golden and many were richly ornamented： you could see at once that they were keys made for opening solemn and secret rooms in palaces， or chests and caskets of sweet.smelling wood that contained royal treasures. But the key which he now put into the lock of the door was big and plain and more rudely made. The lock was stiff and for a moment Tirian began to be afraid that he would not be able to turn it： but at last he did and the door swung open with a sullen creak.
