authority, power, rights
權 centers on the ability to decide or control: authority, power, and the rights that come with that position.
權 combines 木 (tree/wood) with 雚, which likely contributes the sound and may relate to weighing or balancing. The idea of authority may derive from the concept of a standard weight or balance.
A wooden 木 balance scale 雚 represents the power to weigh decisions and enforce rights.
For ケン, imagine a powerful official named Ken holding a wooden gavel: Ken -> ケン, and his authority is absolute.
