Gerry Ostman was a botanist on Tairngaire.
Whilst on Arden, he was kidnapped and duplicated by the Shenn not controlled by Umbra. The duplicate went to Tairngaire, where it was killed. Mentally connected, the death sent the real Ostman into shock. He was taken back to Tairngaire to recuperate, as the Shenn were unable to heal him. (PROSE: Shadowmind)
