Classes

Most standard 3.5e classes exist unchanged in this environment. Barbarians, Bards, Druids, Fighters, Rangers, Rogues, Sorcerers, and Wizards all exist relatively unchanged.

Paladins must belong to one of the Holy Militants, and Clerics all must subscribe to Alexandrian Orthodoxy, and be ordained by an accepted episcopacy, either regional or manifest.

The entrenched social structure and relative political stability of this world allow for a new base class, the Professional, to flourish. This is a variant of the rogue class with a leadership and skill focus, and a rogues defensive mechanics.

Also, while it is true that sometimes members of various cults and Alexandrian Heresies have clerical abilities, they are due to remnants of the Outsider Lord power. As such, they are unsuited to player characters.
