Marblegen

Cosmo, Sam, Luna and Aïssa are mega fans of a game of magic marbles: the Marblegens. They discover that this year, the winner of the Marblegens Tournament will win the legendary Marble Origin Mercury!

Cosmo, Aïssa, Sam and Luna decide to prevent Marcellus King from getting his hands on the Marble Origin: they create the team of Meteors and try to register for the tournament

When an alchemical incident in the Lab creates a spatial loop, the Meteors are prisoners in the Observatory!

Cosmos borrowed the Costello's Spell Book, despite Zumeo's interdiction. Archi and Lardo manage to steal it. The Meteors have to retrieve the book at King's Corp and get back on time to play their match against the Crimson Knights.

The Meteors learn that when Zumeo was young he and Gaia Fulmina, the Olympian alchemist, were snipers on the same team!

A shopkeeper offers Luna a product with exceptional properties (the mythic Uroboros fangs)!
