"The risk of love is loss, and the price of loss is grief – But the pain of grief is only a shadow when compared with the pain of never risking love." — Hillary Stanton Zunin Lyra is still mourning her brother's death, moving through each day like she's underwater—sounds muffled, edges blurred, grief pressing down until breathing feels like work. She keeps going anyway, until a strange pulse cuts through the quiet: a sound only she can hear, threading itself beneath her skin like an invisible hook. The moment she follows it, the world splits open, revealing hidden realms that have always existed alongside her own. The pulse leads to the Signal Domain, where resonance is alive—and listening.
