The Students of Baldesion is an organization of scholars mentioned in Final Fantasy XIV. They are based near Sharlayan on the Isle of Val and are close allies with the Scions of the Seventh Dawn, being involved in studies of the echo, Ascians, and the Umbral Calamity phenomenon.
They are frequently mentioned during the storyline as contacts for Urianger Augurelt and Minfilia Warde. Later, during the Crystal Tower storyline, one of their members, G'raha Tia, is revealed to have been recruited by Cid and Rammbroes Zasertylsyn for the investigation.
Patches 2.1 and 2.2 seem to be building up to their involvement in future updates/expansions. At the end of "A Realm Awoken" the Scions seem to lose contact with the Students of Baldesion. At the end of "Through the Maelstrom" Urianger discovers that something happened to the Isle of Val, as though some great and powerful magic similar to Ultima and Meteor was used and the island was "utterly....gone."
In 4.2 "Rise of a New Sun," the Forbidden Land, Eureka, was released as instanced side content that up to 144 players can explore simultaneously. Upon arriving and speaking with Krile, the player learns that Eureka is a new name for what turns out to have been the Isle of Val, somehow teleported halfway across the world and now seemingly deserted. Krile's goal is to both learn what happened and to see if any surviving members of the Students of Baldesion can be found on the island.
