NPC #48: Roland, Human Wizard
Tales about Roland were once told all across the known world. In his last years all he longs for is someone to pass his spellbook to.
NPC #37: Lilith, Half-elf Sorcerer
A series of arcane accidents forced Lilith into hiding. In order to keep ahead of her pursuers, she never stays in one place for long.
NPC #20: Kallista, Tiefling Sorcerer
Kallista puts her infernal heritage to good use, ruling the criminal underworld through superstitious fear backed up by her talent for magic.
I’m imagining a bit of a home-brew rule where their draconic bloodline changes based on what dragon they killed last. Also, parrot-pseudodragon!
