Voiceless Siren? Sea God’s Oracle!

Voiceless Siren? Sea God’s Oracle! is an undersea fantasy romance about a siren dismissed as voiceless who is married off to a dying sea-dragon prince in her sister's place. Lyra Veyne secretly holds a staggering gift: anything she says becomes an unbreakable oracle of the sea god. Kael Draven is being consumed by Black-Tide corruption, yet he chooses to shield her rather than drag her to the grave with him. Keeping her power hidden, Lyra starts using it to heal him and stand against the Abyss army. All 26 episodes are complete.
