Fenix="Name:  Fenix|Age:   399|Race:  Protoss|         (Templar Warrior)||Data:|Fenix rose up through the Templar ranks alongside his close friend Tassadar.||He is both cunning and powerful, and has fought against the enemies of the Protoss in countless battles. Capable of strong empathy and tremendous rage, Fenix has proven himself to be one of the greatest Protoss warriors of all time.||"
Tassadar="Name:  Tassadar|Age:   356|Race:  Protoss|         (High Templar)||Data:|Tassadar exemplifies the growing rift within Protoss society. Born into a new generation that looks ahead to a dynamic future, Tassadar is frustrated by the stoic view that his elders hold of the past. Tassadar feels that the unbending nature of the Protoss and their inability to re-evaluate ancient traditions will be the doom of this race.||Fascinated by the power and mysticism of the renegade Dark Templar caste, Tassadar hopes to find some way to bridge the gap between these exiles and his masters.||"
