Polychronopolis

The Marchland (Z1, Z2, Z3 and Z4) is ruled by a Marcher Lord with his seat at Castle Argon (his heir usually holds Castle Amra from him). The Marcher Lords have all been descendants of Polychron himself (having had over a dozen children, his line has never come close to dying out). The current Marcher is Lord Theofrastus II.
