A missing piece

1   A flashing light
2   You weren't there
3   Waiting in shadows
4   Unanswered
5   The glass key
6   Clarity
7   Returned
8   The cleansing
9   One last chance
10   A missing piece
11   Forgiven
12   The pathway
13   Fracture
14   Closer than ever
15   Unexplored regions
16   Under the mask
17   It's happening again
18   Regenerated
19   A visitor
20   Reflections
21   Face to face
22   Whispers
23   Something waiting just beyond
