The sea has claimed all
Our pride has sunk below
Where once flags flapped bright
No sign or ruin gives note
Tall spires were felled low
White walls crashed down like foam
The waves have rolled through
Our hearths are dead and cold
Fair gems have waned dark
Their light shines no longer
All songs have ceased now
The joyful live no more
A cloud has risen here
It's shadow leads the van
The Tuatha Dé Danann abandoned Murias, Falias, Gorias and Findias in the northern islands of the world and colonized Ireland. In my interpretation, the cities sank beneath the ocean.
