This race of Djinni are quite different than what you are used to. They have the powers of EVERY race of djinn. And the power to accumulate power from other sources. However, if they choose to accumulate that power, whomever they take it from either is weakened for centuries or dies shortly after. So they try hard not to accumulate power from other sources. This will be custom conjures for this race as they are not wiling to come forth until they see how humans are, and if we are greedy for power and money.
