The Rumbling Sound of Drieghan

Description

There is a small slate stuck in the Altar of Hoom, but is fixed in place, unwilling to budge. The altar has the following text and drawing engraved on it.

When Hoom was embraced by the mountains,
the cries of dragons mourning his death shall echo for eternity.
The tears pouring from the eyes of the dragons
would amass to flood the villages.
Even as several villages are washed away, their sorrow still remains.
Let the song of Hoom bring comfort to those who mourn.

Beneath this text, patterns of the sun, flower, and wind are drawn in that order.

Maybe we should take a look near the waterfall?
