The alternate ending to "little dark age" (previously titled let us sit upon the ground and tell sad stories about the death of kings), where Percy did actually die. You don't have to read that one but it will make more sense if you do. This oneshot replaces chapter three, so read the first two chapters and then read this, to make more sense.
Poseidon retrieves his son, and Camp Half-Blood holds his funeral with everyone in attendance.
Peter Parker ends up in a strange city after the fight on the statue of liberty: so instead of having to be swallowed by depression (he still does get swallowed by depression, this is Peter Parker we're talking about), he gets to start a new life in... Gotham?
(THIS IS MCU!PETER PARKER, just to clarify ^-^)
(Inspired off of Dark Matter by Mysterycyclone)
