Can you use Retreat in response to a Temporary effect (like on Fading Memories), and can you use Retreat during your Awaken phase without a trigger?

Ruling: You can react to Temporary's triggered ability with Retreat. You cannot use reactions during phases (including Awaken phase) unless something is on the chain.

Nuances:

• Reactions require a trigger that starts a chain; phases alone do not provide this trigger
• The Temporary effect happens during the Beginning phase, not Awaken phase
