The Aran are not completed?

No, actaully.
the 2nd one is a Warrior with 1handed sword and a shield [Notice the back of the character].

the 3rd one is a Magician with a staff, or a Warrior with a Spear.
But I think its a Staff. Why? Because, Spear is held with 2 hands (if im not wrong) and the character looks like he is casting a spell or something.
So, can this hint that the Aran Race might be race of Warriors [IF there will be anymore classes]?

do we find a hint of race with multiple weapons?i mean arans that can equp staffs and knuckles and spears?nahhh
i guess this is the cygnus amnesia because cygnus are included in fight against black magician
