Fine fine, I'll play along:

Kan-E-Senna - Leader of the Twin Adder and representative of Gridania and its company

A-Ruhn-Senna - Youngest looking of the Senna family - seen in the Thousand Maws of Toto-Rak communing with the endangered moogles

Raya-O-Senna - Younger sister of Kan-E; opinionated and firy - quite independent

E-Sumi-Yan - Very important to the in-echo storyline of Gridania's introduction; still master of the CNJ guild (?)

O-App-Pesi - Highly adept student of the conjury guildmaster; very sensitive to communing with the forest

O-Isam-Nene - Mentioned during All Saints' but I never met the guy
