This kind of contract will ensure that the child won't die before the parents by transferring Soul Energy via the soul link from both the parents to the child. This will also help the child develop their Magic Energy reserve. When the contract is made, it is required that both the parents agree on the name, then their Soul Energy will be transferred to their child almost instantly, thus inducing nausea and fatigue. In this process, half of each parents' Soul Energy will be given to the child, when the parents get older, the rest of their Soul Power will slowly be transferred to their child with some loss in the process.
