What if... (A Nico di Angelo story)

What if Nyx got Nico as Will, Bob, Small Bob and Nico were in the boat? What if Nico hadn't swore on the River Styx?

It's been 2 years since Will and Nico ventured down to Tarturas, and today is the anniversary of that day. Will never left Camp Half-Blood. He's been waiting for Nico to somehow rise from the ground and and say "I'm back with more trauma!" or something like that. People have gotten concerned about Will; he's been distant, and easily agitated when someone mentions something bad about Nico.

Percy and Annabeth knew what happened, but they hadn't said anything to anyone about it other than the remaining seven, although no one was brave enough to mention it around Reyna. The seven recommend Will take a break, relax, maybe even visit with Nico's parents, but he refused, not wanting to be so close to Tarturas where he might jump in to find a possible dead Nico.

Even Hades and Persephone have been acting weird, much to the God's confusion. The dead have been rising at random times at both camps, causing people to become suspicious.

But one day, a very cold and rainy day, a group of skeletons run to Camp Jupiter and Half-blood, relaying one message: "A demigod has rose from the darkness."

I do not own Rick Riordan's work, nor his characters. This takes place after The Sun and The Star, so I recommend reading it before this so you understand.
