Lyric discussion by voyeurbambi 

like JWB says, I think it's "you set the Viking ship ablaze"

also

"we reached the moon's false icy cauldron"

"where lay the bodies that had been claimed" makes more sense, even if he omits the "that", if he's referring to the white fish...it may also be "where later bodies had been claimed"

and it's my guess "we dove a third, a fourth, a fifth" "bane to the spirit that i craved"

and as he sings "black water", he is also singing "take me down, black water, take me down"
