There are a total of four relics that must be collected. The first relic is in 
the cave in the Tutorial. It can be found in the box of relics. The second relic
is also in the cave in the Tutorial. The third relic is in the cave in the "The
Return" chapter. It can be found on a stand in front of you when you return to 
the cave after Chapter 2. The fourth relic is also in the cave in the "The 
Return" chapter. After collecting the third relic, leave the room and the door
will close behind you. To your right is an open door, and to your left, stairs.
Take the stairs to reach a room with a broken grate. Duck under the grate and
