Semih Lafihna: I showed the report you deliverrred to the Star Sibyl.
Semih Lafihna: Do not worry, as she had already sensed the imminent revival of the Shadow Lord.
Semih Lafihna: However, for the sake of national security, we ask you to keep this information to yourself.
Semih Lafihna: There is no reason to inform the public at this time. The wounds that the Tarutaru received twenty yearrrs ago still have not healed, and releasing this information now would only cause unwanted confusion.
Semih Lafihna: As for you, you can go back to your adventuring. The Sibyl Guards will take the investigation from here.
