Treasures of Aht Urhgan Mission 9
Undersea Scouting
Return to Naja Salaheem to trigger another cutscene. You'll be ordered to patrol the interior of the Alzadaal Undersea Ruins. To enter the ruins, you'll need 1 Imperial Silver Piece, so grab one before heading out.
You may also buy a map of the Alzadaal Undersea Ruins from the same NPC that allows you access to the inside. This isn't necessary for this mission, but if you're interested, bring 3 Imperial Mythril Pieces with you as well.
Head out through Bhaflau Thickets to (F-6) where you'll find Kamih Mapokhalam standing outside a cave. Pay her the fee for entrance, and proceed inside. There's nothing inside to aggro you, so don't worry about sneak or invislbe. Follow the path to the Gilded Doors at (G-8) and you'll receive another cutscene as you approach them.
