Wizards and Rogues of the Realms

"From Waterdeep to Thay, from the great Glacier to Calimshan, wizards and rogues dress, think, and behave in ways that tell the learned observer just where they hail from. Sometimes the differences are obvious - anyone can distinguish a seafaring mage from a turban-crowned spellcaster, or a thief of Lantan from a burgler of Amn. But often, appearance gives no clue: even wizards and rogues of the Dalelands vary from Dale to Dale, though one may look the same as another. Faerûnians are fiercly proud of their heritage, and they carry their native traits with them wherever they go."
