Blackburn is a non-playable character in original Final Fantasy XIV.
Blackburn is a Path of the Twelve walker who is investigating Limsa Lominsa. He meets and has a brief conversation with the adventurer in God's Grip. Due to a vision of the echo, the conversation is interrupted and the adventurer loses consciousness. Blackburn recognizes the phenomenon and carries the adventurer to the Adventure's Guild. Blackburn does not wait for the adventurer to wake up but leaves an invitation for him to visit the Path of the Twelve in Ul'dah.
Once the adventurer makes his way to the organization's headquarters, Blackburn is seen alongside the walkers from other cities welcoming the adventurer.
