Von Cronts displays a very abrasive attitude, at least towards Leif Rimnis. This may show that he is adverse to authority, or that he is adverse to those who succeed more easily than he does. Either way, it shows him as having serious insecurities about his own social stature.
Von Cronts was known by name and reputation to General Von Scnovts. That may have been one of the reasons he was selected for the mission to survey the Shcots, working under the orders of commander Leif Rimnis. During the mission, the group was separated and Von Cronts has made no further contact with the Garlants since then. He is presumed killed by Barlos.
