Not really spoiler just a better of explanation of what we already know:
The Sovereigns (formerly known as monarchs) and the Rulers have been waging wars against each other for a long time. The Shadow Monarch is the source of Sung Jin-woos powers but we don’t know how or why yet. The rulers can lend their powers to vessels. Four of the national level hunters are those vessels. The other monarchs are going around killing those big hunters since they are vessels. Also the Monarchs and the Rulers are planning on using earth as their battlefield for their big war.
