Ridcully spent a year looking into the recent trend of Chaos Psyker being pulled into Warp Rifts on Avernus. He was able to determine that they were being pulled in by Daemons of the Changer of Ways, which are avoiding the majority of Avernus' response by not leaving the Warp for more then an instant and speed. He has no clue about what the psykers are being ued for but you can see many ways in which a Daemon could benefit from having control over a powerful Avernite Psyker, particulary as they were all young enough to turn into Chaos Space Marines.
