Corinth hired Kroner in Deal following the The Doomed Attack on the Merloc Lair, for the journey to Opportunity and to accompany her on further dungeon-delving efforts.

One of the conditions of his employment is that, should Corinth meet her final end, Kroner is to be given her magic shield, an ancient dwarven artifact, so that he can bring it back to the dwarven homelands.

In journeys to the Bleak Academy, Kroner has taken a grievous head injury and lost an arm. Still he travels with the party. While addled in the depths of Bleak, he was heard to be muttering about his brothers and father, apparently some kind of dwarven noble family.

Dismissed by Corinth, retained by Carcophan as a magical engineer. Disappeared from Opportunity during the raid of the Crocodile Temple; seen in the company of a witch at that time.

Surfaced in Ironbridge with a scaly reptilian arm. Appears to be part of some Dwarvish organization.
