Nomad

Male
Male nomads are predominantly type 9 and type 6, which makes them good axe tech sparkers. Their stats are above average in STR, DEX, and SPD, which means if in the early to mid stages you need an axe sparker, you can do worse than these guys. (Though, you can get the privateer probably just as easily). Esen is noted for being a swordmaster & a dark mage, but you'll have to work for it, as he comes in with no proficiancy in it (he & Batu are great counter baiters, though....).

They are all named after rulers of Mongolia.
 * Esen can be any one of: Esen Burqa the 1st, the 2nd, or Esen Tayisi (but most likely Tayasi).

Female
Female nomads, on the other hand, are better bow users than melee warriors. (Though, they have nothing on the hunters) Fatima, by the way, has a dark status of 23, which makes her one of the best dark magic users out there if you decide to go that route. They can sometimes come out as surprisingly good regular casters too! Aria has a casting power of 40, which is higher than all of the female free mages! If you do choose to go down a melee path, however, Azuiza & Doniya are your gals (just be sure to train them hard).
