</aside>
The Castle Heart is an essential structure that powers all your castle's structures and defenses. It can only be built on territorial land, and in so doing claiming the entire territory as your own.
Castle Hearts require upkeep in the form of 
Blood Essence.
This essence is stored in castle power slots, each of which has a 250 Blood Essence capacity. The Castle Heart has a default drain rate of 24 hours per 180 Blood Essence. Running out of blood essence causes your territory and its structures to decay, pausing their functioning until it's refilled.
The castle heart is required to be built on the ground floor, but it does not need to be placed inside the castle you eventually build. As you build your castle, your initial foundation tiles must be connected to it. Once the tiles are in place, additional structures may be built on top of them. Enclosing 
Castle Flooring tiles with 
Castle Walls, 
Stone Stairs or the like will generate a roof and activate the enclosed castle room bonus for all structures inside.
The Castle Heart may be moved freely within its territory and need not connect to a foundation tile. It is also possible to move the entire castle to a new territory, using the 
Castle Relocation Heart.
Upgrades
Your Castle Heart can be upgraded to increase its max Border tile capacity, its Servant count and its castle power slots.

Castle Heart Actions
Rivaling castles may either have their defenses disabled, destroyed or claimed with 1, 1 or 3 Castle Keys respectively by interacting with their Castle Heart. (destroying and claiming are for Merciless PvP Servers only)
Keys can be used on a rival Castle Heart as long as you have access to it, regardless of any castle heart attack status or raid time window.
When a castle's defenses are disabled, the following effects occur for 10 minutes:
- Temporarily reduces the health of all structures within the castle.
- Enemy players may use paired
Castle Teleporters inside the enemy castle. - All walls, doors, pillars, entrance barriers, and windows become immaterial, allowing players to simply walk through them.
- All chests / storage, except the
Vampire Lockbox can be instantly looted without a cast time. - The Owner / Clan may not respawn in coffins or use
Castle Waygates. - Servants cannot be revived.
When a castle is destroyed, every structure will be dismantled and the territory claim is revoked. All storage containers will have their loot dropped in bags near the previous Castle Heart.
When a castle is claimed, every structure will be transferred to the claimant, including Prisoners & Servants.
The type of key required must correspond to the level of the Heart attempting to be accessed.
For example, a Golden Castle Key can only access level 4 / 5 Castle Hearts, not level 3s.
On PvE servers, even though there's no threat of raiding, castles may still be destroyed for free if in decay.
Finally, a Castle Heart may be voluntarily Exposed for 5 minutes, allowing for voluntary transfer of ownership.
