Guesses About The Upcoming Norse Series
The villains will be the Jotuns, with Surtr as the Big BadOf all the figures in Norse mythology, Surtr is one of the few who is both uniformly BAD and not a Sealed Evil in a Can. The story will take pains to show the differences between the Jotuns and the Greek giants.
Loki will be be an ally of the heroes... but not the godsHe's too obvious to be the villain. Instead, Loki will be a third faction, opposing both the gods and the giants. But rather than opposing the heroes, he will try to get them on his side. There will probably be a time (perhaps one book) where the heroes are largely working for Loki.
The heroes will set up their base of operations in the BronxThe Greeks are already in Manhattan and Long Island, and the Egyptians are in Brooklyn. That leaves the Bronx, Queens, and Staten Island. Queens is adjacent to Brooklyn and between Manhattan and Long Island, so it's unlikely. And Staten Island is something of a Butt Monkey.
there will be a comment about the Marvel Thor and LokiIt will go along the lines of 'I don't look like that, but the movies have empowered us beyond compare'
Rick Riordan will follow up on the Norse mythology series with a series on Mesopotamian MythologyNew York is quite literally the Land of Two Rivers - The Hudson River and the East River, both mentioned in the final Percy Jackson book. And a Troper can dream, can he not?
The series will be followed up by a major crossover eventWORLD WAR MYTH!
The "Curse of the Bambino" was a literal curseStemming from a dispute between the Greek and Norse gods over Babe Ruth transferring to the Yankees.
Loki will be an Unwitting Instigator of DoomBoth Percy Jackson and the Olympians and The Kane Chronicles started by focusing on a typically villainous figure from their own mythology before revealing them to be Good All Along and an Unwitting Pawn respectively. Similarly, the series will begin with him setting off a set of events that leads to the Big Bad beginning their plan.
The protagonists will be Like Brother and SisterPercy Jackson and the Olympians had Percy and Annabeth, who eventually became a couple (although it took them long enough), while The Kane Chronicles had Carter and Sadie, who were brother and sister. The Norse protagonists will be friends but very clearly NOT interested in each other. They will do the "blood brothers" ritual at a key point in the first book.
