Alrighty... This could be a bit long. ^^;

Name: Kar'Naj

Race: Draconian (As in, dragon-man)

Age: 60 (This isn't very old for a draconian)

Class: Warrior

Weapon: Queen's Wrath: This is a longsword Kar'Naj himself has forged. Blessed by a cleric of the Dark Queen Takhisis, it is sharper and more resistant than a normal blade, and exudes a dark aura. The hilt is crafted in the likeness of a five-headed dragon, the heads stretching toward the sword's tip, and the outstretched wings acting as a crossbar.

Armor: Dwarven chain mail: Chain mail of dwarven make and design. It was crafted by a highly skilled blacksmith, considered so even by dwarven standards. It was crafted to last, and last it does. This chain mail is the only armor Kar'Naj trusts, since it is very reliable.

Appearance:
-Eight feet tall
-Intense, cold ice blue eyes
-Silver scales cover the entire muscled body
-Taloned hands and feet
-Somewhat long, yet stubby tail
-Large wings attached to his shoulderblades
-Long, dragonlike snout
-Sharp fangs meant to tear and rend

History:
-Served with the Blue Dragonarmy
-Became weary of the army, how disorganized it was, and left
-Has been wandering ever since, in search of new, stronger opponents to battle

Skills: Kar'Naj is a most ferocious warrior, skilled in the art of manipulating the sword. His large body does not hamper movement; in fact, he retains agility and suppleness. When the adrenaline kicks in, he virtually becomes a killing machine; his blows become far more fericous, gaining in strength at an alarming degree. The attacks become more frenzied, aimed with less accuracy, however, and they leave Kar'Naj open for strike more than he'd like to.

Name: Nadare

Race: Part dragon-ish (will be further explained in physical description)

Age: 25

Class: Assassin

Weapons:
-Throwing daggers (10, all in sheaths hidden across her entire body)
-Katana (Hangs in a sheath at her side)
-Silvery orb (Used to increase the power of her spells [helps her channel her energy more effectively])

Armor/clothing:
-Light elven chain mail worn beneath loose black shirt
-Black trousers

Appearance:
-Approximately 5'5"
-Faint traces of scales are seen on the face, as though an artist had traced the fine lines
-Rest of body is covered in scales (Note, however, that it is completely hidden from view most of the time)
-Jet-black hair
-Crimson eyes
-Hands are more of a cross between hand and talon, with long fingers each ending in a short claw

History:
-Has trained to be an assassin since the age of five
-Began taking on actual assassinations at the age of 15
-Is now a wandering assassin (ie, never stays in one town for long)
-Occasionally, challenges powerful fighters to test her skill against their own

Skills:
-Expert in stealth
-Swift
-Highly accurate dagger thrower
-Skilled with the katana, in the way of the Silent Wrath (technique studied)
-Minor attack spells (bolstered through the use of the aforementioned silvery orb)
As for WHICH spells exaclty, and the techniques Nadare employs, you'll have to fight her to find out...
And I'll update as needed.
