The Implicit Maze is a system of mana paths or leylines through the guildgates and districts of Ravnica that has manifested after the Guildpact was destroyed. On instruction of Niv-Mizzet and using Jace Beleren's notes, it was discovered by Ral Zarek. The maze was created by Azor I to be revealed in case the Guildpact dissolved. In this way, the founder of the Azorius Senate tried to foster an atmosphere of peaceful collaboration. At the end of the maze in the Forum of Azor lies great power. In order for it to be solved, all the guilds of Ravnica must participate at once. Niv-Mizzet has announced that each guild will send one champion as its delegate in the running of the maze. At an appointed time, the champions meet at the Transguild Promenade, and embark on a race through the twists and turns of the maze. The one who triumphs, gains the power behind it for their guild. Others fall to its dangers.
