Guildpact Guilds: The Izzet
The Izzet run hot and cold—literally. In fact, they keep nearly everything running, from Ravnica's heating networks to its water systems. The undisputed masters of spellcraft and invention on Ravnica, they're the only guild that understands metamagic: how magic itself works. Led by the capricious and unfathomably brilliant dragon Niv-Mizzet, the Izzet magewrights endlessly create and destroy, driven only by passion for discovery. Experts in elemental magic, the Izzet use elementals to guard their alchemical labs and power their turbines. They've even created their own crossbreed elementals called weirds. Unlike most other guilds, the Izzet fail to see the importance of power, dominion, or wealth. The rabid pursuit of knowledge is the guild's only concern.
The Izzet have designed most of the city’s infrastructure, such as systems for delivering water and heat. They are the inventors and designers in this world, although their facilities and alchemical labs are often powered by bound djinni, efreeti, and elementals.
Using alchemical devices to amplify their spellcasting, wizards tend toward elderly. But they’re not all old, and they’re not all men. Their costumes (flamboyant, due to the size of their dragon master's hoard) feature copper and gold, largely for their conductive properties.
Izzet soldiers also revel in flashy and ornate suits of armor, suitable for displaying their allegiances.
