- Vassal nodes must remain one node stage below their parent node.
- Vassal nodes give excess experience to their parent node and may have their own vassals; so long as they fall within the parent node’s zone of influence.
- If a node is capped and is both a vassal and has its own vassals, any experience earned from itself or its Vassals is first applied to its own deficit. Experience beyond that is then sent to its parent node.
- Vassals are subject to the government, alliances, wars, taxes, and trade of their parent node, and are able to receive federal aid from them.
- Vassal nodes cannot declare war on their parent node or any of their vassals.
- Citizens of vassals are bound by the diplomatic states of the parent node.
If a Node is a Vassal Node and is capped from advancing further, it first applies any experience earned to its own deficit (see Node Atrophy section), and then applies excess experience earned to its Parent Node. If the Parent Node advances and the Vassal is able to grow, it becomes uncapped. If a Node is capped and is both a Vassal and has its own Vassals, any experience earned from itself or its Vassals is first applied to their own deficit. Any experience beyond that is then sent to its Parent Node. – Margaret Krohn
