The Saga of the Clan of Rhaaztum

The following is a translation from Giant to Common of the words that were inscribed upon the central pillars in the ruins above where Kobolds now dwell, as seen by the party during their second visit to the site (first with ability to translate). Words/phrases denoted in <angle brackets> are uncertain or variant translations of the original.
So it was, in ages long past, that the ancestors of our ancestors <ruled/shaped> the elements of <the world/everything>. From such a <mighty/noble> lineage, in that of Cloud Giants, second in order to only the <eminent/aloof> Storm Giants, did the illustrious Rhaaztum arise. At the feet of <tall/great> mountains to the north, he held his domain, wherein the power of water was at his hand.
But lo, at his moment of greatest triumph, did <dragons/vile beasts/foul lizards> seek to intervene! As the heavenly tides of Evil turned to Order, Rhaaztum summoned forth <ten thousand/innumerable> creatures to assert his <dominion/protection> over the lands. The <insolent/weak> druids of those lands rejected his just <rule/guidance>, and turned in rebellion to our eternal enemies. In turn did the <dragons/vile beasts/foul lizards> three, of fire, thunder, and lightning, <charm/conquer> the peoples of those lands and lead them against the <mighty/noble> Rhaaztum. With trickery and deceit did they wage battle against the Clan of Rhaaztum, and many were <killed/delivered to the great beyond>. But the Clan was not without trickery of its own, for amidst the battle, the most high Memnor guided us here, away from the waters below to the air above.
At such time, below this summit, did <lair/sleep> the <dragon/vile beast/foul lizard> of cold, Freldemalae. In swift battle, and with a mighty blow to its wretched jaw, it was slain by Rhaaztum, and thus began our <dominion/protection> over these southern peaks. For many centuries, our <mighty/noble> Clan <ruled/guided> the peoples of mount and vale in prosperity and peace. In this time, the <tall/great> Rhaaztum gave his last breath, and <remainder illegible due to defacement>.
With our numbers diminished, a lesser Clan might have perished. Though the peoples of these lands grew <unruly/dishonorable> as we withdrew our hand, we persisted, remaining above them all in our rightful heights. And so it is, as we inscribe these words into stone, that the most high Memnor guides his <mighty/noble> people again. With the rift of air turning frigid, and its icy grasp beginning to reach across these lands, we know where we must go and wait. Be it decades or be it centuries, we will stand ready, for we are patient and we are strong. We will return, and we will <rule/guide> all the lands of our ancestors once again.
