Ravnica: City of Guilds

Ravnica is a huge city that covers all its plane. Each of its quarters are as big as continents and controlled by guildes which are affiliated to two colors of mana. During ten thousand years, those guilds made war to each other. That’s hy they decided to sign a non agression pact called the Guildpact. The story begins a short time before the celebration of the 10.000th anniversary of the pact but recent events could make the war start again between the guilds of Ravnica.
