From LOTR-TCG Wiki
Shadow may refer to either:
- Shadow Phase, the second of the six phases in the turn order
- Shadow (Alignment), one of the two sides in this game. They are the enemies of the Free Peoples, and led by Sauron as he seeks to throw Middle-Earth into darkness.
You may also have meant Shadows, the set. You may also have meant the Block that set appeared in, War of the Ring Block, which was also occasionally referred to as "Shadows Block".
