Sorcerers

Sorcerers are a fractious bunch, particularly because their power comes from an accident of birth and not dedicated training. Still, some family lines are prominent and consistently produce sorcerers, and other sorcerers find themselves bonding together over common roots.
Draconic sorcerers are occasionally well received by dragons and dragonborn, and other times hunted by them. This mixed reaction makes many draconic sorcerers leery about associating with others of their kind; dragonborn sorcerers are a notable exception to this.
Wild Magic sorcerers don’t typically feel a bond even with other Wild Magic sorcerers; the nature of their abilities defies reason, and most are happier being the only sorcerer in their group. Wizards and bards make better company, as many Wild Magic sorcerers prefer someone with more stable arcane talents around them.
Storm sorcerers are typically regional more than familial, though several cultures revere them and give them elevated importance. Storm sorcerers often head small coastal communities or find gainful employment in larger ones, and as a result, are among the most likely sorcerers to associate with others of their kind.
Shadow sorcerers are off putting to most, and when they gather, it’s often at low key events. Though not bound to be evil, their association with death and darkness colors their outlook as well as the outlooks of those around them.
Favored Soul sorcerers often have a celestial background and are only too happy to provide healing for others (which, many point out, leads to a comfortable life). They associate with clerics more often than other sorcerers like themselves, though that has more to do with rarity than anything else.
Pyromancer sorcerers (found in the Kaladesh PDF) crop up far more randomly than one might suspect. Many scholars have tried to find patterns to ascribe appearances to proximity to magical fires and the like, but the appearance of these sorcerers seems to be as random as it is destructive.
