[i]remember the songs of those coming before.[/i]
[i]On dark wings of shimmering blue[/i]

[i]protectors; when it comes, it leaves none untouched. [/i]

[i]Soth, once thought glorious, betrayed us.[/i]
[i]Him and his concubines, his golden warmaidens[/i]
[i]fought in the west, among the mountains[/i]
[i]and vales, in the snows and the skies. [/i]
[i]When Soth heard of Yakkarin's fall, [/i]
[i]he escaped in the night, leaving[/i]

[i]It fell on Ashtaar, Yakkarin-twin,[/i]
[i]to hold the city himself. Though[/i]
[i]very young and yet untrained,[/i]
[i]he held the roads for years[/i]
[i]against the screaming horde.[/i]
[i]When their brothers rose[/i]
[i]from the ocean and the sewers,[/i]
[i]they dragged him down deep.[/i]

[i]Remember the song of the Ashrain dragons[/i]
[i]for history is naught but a pendulum[/i]
[i]swinging back to forth and back,[/i]
[i]until time ends. [/i]
