Hi Ambroas,
You will need to come up with an impressive backstory, complete history and well written Character Sheet to explain your concept and then submit to the Help Desk. In a nutshell, the Ceruleans are a cult of Akalaks that have no self control of their conflicting personalities, and are generally looked down upon by Riverfall citizens. They are deemed dangerous to society and after a session with the Council of Elders, they are marked with vivid facial tattoos to warn all who see them that they are lowly Ceruleans. Because they have such low status, they forgo the right to a surname and any honor. Riverfall is filled with many honorable, law abiding citizens, male and female. We have a great write up in the Wiki that details what it is to be a Cerulean-and it's not favorable.
