Need a longevity potion? No? How about a love philter, golem, clockwork assassin, or djinn servant? Just ask The Artificers Guild, a federation of associated alchemists, construct crafters, and summoners devoted to their drafts and their profits. Need their help and they're a resource beyond price (though that resource never comes free). Stand in their way and they're going to teach you why their wares carry such a high price ... the hard way.
The Artificers Guild is a group of mystic NPCs to add to your Mutants & Masterminds campaign.
