When Romans, Greeks, Hunters, and Magicians get together for the holidays, what could possibly go wrong? Oh, I dunno...How about a magical penguin army, cursed mistletoe, gryffin rides of doom, and a holiday cheer apocalypse? Percabeth, Caleo, Jasper, Tratie, Frazel, Zarter, and Sadie x Walt/Anubis! Solangelo centric! HILARITY WARNING: if you die of laughter, it's totally my fault!
