The only two people who were seeking the Promised Land were either Sephiroth or Aeris. Aeris dies on CD1 and Cloud continues his search for the promised Land on CD 2 by going after Sephiroth.
On CD 2, Aeris has almost no relevance, except for the part of the activation of the White Materia.
Edit - You could also mean Hojo or Rufus, but I would put them all into Shin-Ra. That would be a little shaddy though, since their search is a bit intermitent during the game.
