" Other rumours, equally venerable, tell a different – that long before the age of mortals there was a great war between the dragons and a brutal race of titans. So lasting and terrible was this conflict that the bones of the slain are still scattered over the blighted lands. It is said that the titans eventually won this war to bring to an end of the Age of Dragons. This ushered in the Age of Tyranny, when mortals served no purpose other than enslavement, a tyranny that was ended by the coming of the Arinn.
If such be true, deliverance surely came with a price. – Ussha De Danaan: last High Architect of Ossierel "
