If a Kevesi or Agnian die by any means other than Homecoming, they are born again in the same cradle they were in as part of the cycle of rebirth. Even though most cradles are located in Keves Castle and Agnus Castle respectively, there are still some cradles stored outside of the castle, such as in the City's Module Warehouse, and the Lost Colony.

Cradles don't seem to able to release soldiers automatically, there has to be an individual to interact with the cradle in order to release the soldier inside, as how Ethel was accidentally released by Cubibi during a game of hide-and-seek. Cradles are also movable, as the Lost Numbers has seized many cradles from Keves Castle and cradles were being carried to the Cradle Convoy Shelter at the Great Sword's Base.
