Titan

"It shapes the Stone. It is the Stone. It sculpts the world within and without."

- Primeval dwarven carvings

The Titans are ancient beings that dwell deep beneath the earth. They are massive creatures who sing in the Stone, shaping it.

Background
There is no mention of the Titans in Orzammar's Memories, although there are at least two dwarven texts which describe them predating the First Blight. The knowledge of the titans was likely erased from the Memories by the Shapers as it would be upend the entirety of dwarven culture and faith.
