Jägertroth

The Jägertroth appears to be the Jägermonster's set of fundamental duties (or perhaps beliefs), linked inextricably with their loyalty to House Heterodyne. We know this loyalty entails (or at least implicates) obedience to the Heterodynes, keeping Heterodyne secrets from outsiders, and not giving up looking for a new Heterodyne, even when there isn't really any hope.

It is apparently possible to renounce the Jägertroth, in which case one is no longer a true Jäger- pointy teeth not withstanding.

"Troth" is an old word for "oath," but it is unclear whether Jägers swear an actual oath, or whether the tenents of the Jägertroth are, as it were, built in.
