Again, from the KGB Oath...

I will, to the best of my power, uphold and defend the KGB Constitution while preventing all offences against the persons and properties of the KGB Nation.

Since BDO is an Open Faction, yes, there is no restriction against joining a rival guild, but that does not absolve one from the obligation to never commit an offense against a member of the KGB Nation.

Our obligation under our Oath transcends any individual game. When one joins the KGB, one does not join a mere guild in a single game. One joins the community that is the Great KGB Nation.

To the everlasting glory of the infantry...
