The Celestial Sorrow Demon Monarch is a Celestial Being, one who has not joined the ranks of the Godslayers.
The reason why he appeared in the great war of the Celestial Human Realm is that he was affected by the curse of the Chaos Seventeen Ancestors, which forced his residing world to be connected with the Celestial Human Realm.
Of course, the Celestial Sorrow Demon Monarch is not a character with benevolent intentions or compassion for all beings.
He did not develop any feelings of concern just because his world was drawn into the great war of the Celestial Human Realm.
On the contrary, as a qualified "Civilization Seller", the Celestial Sorrow Demon Monarch saw limitless business opportunities in it.
The so-called "Civilization Seller" essentially refers to deities who treat races and civilizations as "commodities" for trade.
