They were ministeriales of highest administrative rank and reported directly to the imperator being responsible for the system of feudal tenure of the castle.
In 1194, the Holy Roman Emperor, Henry VI was accompanied by marshal Eberhard of Anebos during the campaign against Italy.
It is assumed that the feudal tenure of the castle was passed on to the family of a seneschal called Philip I of Falkenstein.
His wife, Isengard, transferred the castle back to king Conrad IV of Germany.
This is evidence of the expiry of a tenure due to the lack of a male successor, which would require the return of a castle to the king.
