Interested, will edit post with cs as soon as I'm done.
EDIT:
Name: Lyarea Exenris
Appearance:

Age: 21
Race: Incarnus (human)
The Incarni are the human vessels of Neris, a spirit of darkness, madness and the unknown, and able to attune to magical artefacts belonging to their predecessors. They age slower than humans and can live for centuries, though they are not immortal. Their powers vary from incarnation to incarnation, but are always related to his themes.
One power every Incarnus possesses, however, is leadership and command of the Whispering Council, a legion of seemingly all-knowing voices. Normally they can only be heard by the Incarnus, but can be ordered to make themselves audible to others. Prolonged exposure to their sound induces paranoia and insanity in all except the Incarnus themselves. Apart from a small number which perpetually gibber or laugh insanely, the voices are affable and willing to provide advice or answers, but beyond the simplest yes/no answers they always come at a price.
Class: Rogue - Besides her connection to the Whispering Council, Lyarea has perfect night vision, heals ten times faster than an ordinary human in the dark, and has increasing strength and speed the darker her surroundings are. However, in the daylight she has the typical strength and speed of a girl her age. Instead, she relies on her skill with a dagger, lock-picking and stealth. Her only magical item is a theatre mask belonging to a previous Incarnus, which makes people overlook her.
Personality: Lyarea is rather passive as a consequence of following the Council's advice for most of her life. She tends to "space out" frequently, but is capable of being alert and coldly pragmatic when she wants to accomplish a task. She is loyal to those she considers her friends, but views most moral systems as absurd and not fully applying to her. She has a cheerful and pleasant demeanour most of the time, interspersed with bouts of melancholy and homesickness.
History: Lyarea was born in the city-state of Ferremis to Vradi parents. The Vradi were a persecuted minority, shunned for their worship of what was seen as a dark spirit and forced to live in catacombs beneath the city. She was identified as an Incarnus at two years old and brought to the temple priests to be raised by them. They taught her about Neris, the finer details of their religion and how to tune out the endless noise of the Council. As she grew older her formal lessons decreased and focused more on her responsibilities and duties as an incarnation of their god. She began using her free time to explore the tunnels and use the Council in ways a child would. The temple priests warned her to be wary of them, that they always demanded something in return for their answers, but she ignored them. After all, they didn't ask for much. What harm was there helping out the butcher for a week, or sneaking into the granaries, or trying to traverse all the living chambers at least once without anyone spotting her?
This continued until she was 16, when a religious clash between a group of Vradi and surface citizens sparked riots citywide. She was captured along with several other Vradi while looking for the temple priests and taken to the minister's mansion as servants. She turned to the Whispering Council, asking for a way to free herself and her people. For the first time in her life, they fell silent, and a voice she had never heard before this moment told her that it would come at a cost. It asked if she was willing to accept. In her desperation, she agreed.
What followed was three years of planning and coordination with the other Vradi, and gas-lighting the minister and his household to drive them to madness. One day, the Council told her it was time to act. In one night the Vradi slaughtered the minister and his household in their beds, and used the tunnels Lyarea had mapped out as a child to assassinate all the other government officials.
It was only then that the Council revealed their price: she had to leave the city there and then, never to return. She pleaded with them, and the same voice which had warned her about the price of their help allowed her three hours to prepare. After taking her dagger, some lock picks and supplies, the voice directed her into the tunnels, eventually coming to a chamber containing the artefacts of previous Incarni. She found her mask there, and left.
Family/Relationships:
Parents - killed in initial rebellion.
Temple priests - mutual respect and regret at parting.
Other: The tattoos on her arms are a custom of the Vradi.
