The Remaining

A year since Gaia's defeat.
A month since Apollo's trials ended.
Two month's since Piper's death.
The night after the celebration of the Greeks, Romans, Hunters and Amazons.
The disaster began.

Only four remains of the Greeks and Romans. The rest have joined the ranks of Hunters or Amazons.
Only the remaining four received the unwanted blessing of the gods.
The remaining four blessed for a new adventure.

Percy has collapsed with grief.
Jason is struggling to deal with the deaths.
Leo came back from the dead, only to see everyone else pass away.
