Hammer of Balance

You found a hammer at Akum's pagoda near the Garmoth's Nest. Let's figure out a way to find the slate.

Year 32 of the Sherekhan calendar.
For half a year the rains ceased to fall.
Blame was placed upon Turpa mountain,
said to have been blocking all the rain clouds.
Thus with his mighty hands, Akum moved the mountain,
and the mark left by his palms shall be witnessed by generations to come.
A ring was sealed on Akum's ring finger
and lay buried within a marked location.
