Complete the Sentinel's Game by connecting the two red statues.
As you place the statue in its place, several other stone statues appear in the room. One more ruby-colored statue also appears, in a small enclosure on the far end of the room. You hear a voice:
"The Sentinel watches.
The Sentinel protects.
The Sentinel's vision never falters."
That red statue on the other side of the room looks important. Perhaps you should try to connect the two red statues?
