Son of Death and son of Life
Former hit by Time Lord's scythe
Griffin trio assist the two
To make the potion ocean blue
Weapon in snake speaker's throne
Keeping Half-Bloods from their home
Blood of Death and Blood of Life
Clockwise once and counter thrice
Smelted blade of Time poured in
Pour potion as time begins
Portus when the clock strikes nine
Brings the two back to their time
So... I guess mull that over for the weekend. Put your predictions in the comments, I would love to see your ideas!
