Marienburgers are one of the three "subfactions" that a player can choose for their Human Mercenaries warband in Mordheim, alongside Reikland and Middenland. A Marienburg Mercenaries warband gains two special rules to reflect their origins. Firstly, they gain a +1 bonus when attempting to find rare items. Secondly, they start play in a campaign with +100 gold crowns to amass their warband with. These traits represent their connections to the merchant's network of Marienburg, and the subsequent wealth it gives them.
