Dragon goddess of the sea.

After solving the puzzle of the observatory and unlocking a hidden chamber, you unearth the Rune Bones;

You discover an indentation in the wall that is shaped like a five-pointed star and set in the crown of the constellation Merrin, the Dragon goddess of the sea. You hear a click, and then a grinding of gears. A door opens in the wall before you and leads you into an ancient durgolium chamber. Inside the sack, you find a set of oversized knuckle bones, carved with runes, an ancient tool for divination. The bones hum quietly and glow when you touch them. - Bogroot Demon (RPA-ADV6)

Good old Buurglap, god of war
Entered Ulos through Kethra’s door.
Sailed Merrin’s seas against the tide
Crashed his ship and nearly died.
His grieving lover, god of death
Kissed his lips and restored his breath.
Now good old Buurglap can lead to slaughter
All your beloved sons and daughters. - The works of Bertram Hoogna, Servants of Azema (GS-ADV2)
