There are many blue skinned troll tribes, and a short name like Yara. No affixes to the name give you nothing to go on - Zul'Yara might reasonably be expected to be a master of atleast one form of voodoo, Yara'Maz might be either a tribal leader or one tapped to inherit that mantle when the leader died. But a simple 'Yara' suggests either a young troll woman with few accomplishments to brag about, or no heritage worth flagging.

You know none of these people, though "Ignaeus" is the name of the ancient tribal king of the Alteraci tribe whom King Thoradin of Arathor bested in combat and took on as a brother and fellow general in the ancient trollwars. Ignaeus was given the name "Trollbane" for his heroism, and his descendants carried that name eventually to the throne of Strom. Obviously the real Ignaeus Trollbane is long, long dead; but the name is most commonly given to Alteraci sons more than Stromic ones.
