Kane was taking a big risk by doing it. If his Kingdom fell into the hands of some evil or corrupted King, then the economy of his Kingdom would only get worse. This is not what Kane wanted in any situation.
One of the reasons why Kane approached the Istarin Empire is because these days the name of the Istarin Empire was almost everywhere. Everyone knew how in less than 5 months, the Istarin Empire went from being the smallest Kingdom to the biggest empire in the Eastern region. Also, after extensive detailed research on the Istarin Empire, Kane started to feel that he can trust the Istarin King.
So far even though the Istarin Empire has become the strongest Empire in the Eastern region, the Empire has never used its power to bully any of the neighboring Kingdom. However, that did not mean that the Istarin Empire was weak. The Empire has completely destroyed anyone who tried to attack them or even think of doing any harm to them.
