Achaeans are another name (roughly) for the Greeks. Mine were colonized off the coast of what is now Morocco in approximately 86 BC while searching for Atlantis. They were hoping the Atlanteans could aid in a final struggle against the Romans but were whisked away to another world. 

There were certain things expected of a student in Greece. They were to be able to recite  both history and poetry, speak in a court, play an instrument, and wield spear, sword and shield. The magic of the new world is forbidden at the university. Learn the basics first and your magics both elsewhere and afterward.

Suggested Characteristics

Students come from many walks of life and for many reasons: because their status says they must, boarding school is better than a tutor, trying to make a better life for themselves, or with the intent of becoming a good general in the king's army. Personality traits, ideals, bonds, and flaws from nearly any background are appropriate.
