A female Knight Radiant mentioned Harkaylain to Dalinar when he appeared as Heb in the Starfalls vision, which took place in the year 337 of the Eighth Epoch. Harkaylain was said to be able to predict Desolations with some accuracy.
Dalinar later revisited the Starfalls vision, this time embodying the female Radiant. Dalinar claimed that there was a problem with the Radiant's "living" Shardplate, hoping that her companion, the Starfalls Windrunner, would reveal some information about how it worked. However, the Windrunner told her to talk to Harkaylain or her spren if she was having problems with her Plate.
The two Radiants each mentioned Harkaylain in a seemingly familiar manner, which may indicate that he is also a Knight Radiant, but this has not been confirmed.
