Castle Heart

Castle Hearts are the first thing required to be placed before you can build in your territory. Purchasing tiles after building the Castle Heart allows you to build additional structures on the purchased tiles.

Castle Hearts require upkeep in the form of placed in their inventory. Running out of blood essence causes your territory and its structures to decay, and prevents crafting stations from functioning.

The castle heart is not required to be placed inside the castle you eventually build. Its only requirement is to be connected to the territory, although it will be vulnerable to attack if placed outside a walled area.

When moving the castle heart it is important to keep in mind that it can only be moved onto a tile without a border or floor. When moving the castle heart also make sure that every tile is directly connected, otherwise you will be unable to move the castle heart or demolish any tiles that would separate any tiles from the castle heart.

Upgrading
Your Castle Heart can be upgraded to increase its max Border tile capacity, its Servant count and its castle power slots.
