percy gets sent to tartarus, but what else is new

Nico might have been planning on leaving camp, but that doesn't mean he appreciated being sucked into another dimension with no way of getting back. Since it seems he's stuck in this strange world, he might as well get used to it and maybe make a few friends along the way. [Longer description inside, mostly Nico's pov, canon-typical violence]

Just like it sounds, the fates were bored and decided, eh what the heck, let's cause as much chaos as godly possible. You'll see what I mean.
