Nicholas is not from the royal family, he has no royal blood. His father's sister, his aunt, married the King and she became the Queen. She was the mother of Noah, Dylan and Isabel. So this make Nicholas their cousin, even though he has no royal blood. Nicholas is from the 'De Grace' family which is a pretty old and powerful house, his father is a Duke btw. Since his father is the brother-in-law of the King, and a poweful nobleman, he and his sons were invited to the ceremony as well. The other royals are not so close related to the main royal family, since the last two kings (the current one, and his father) were both an only child since their siblings died before reaching adulthood. So Noah, Dylan, Isabel and even Alex have no close cousin from their father side. The royal members all have royal blood from a long ancestry, they all have golden eyes and 'technically' also "royal magic" (light or lightining magic). And, although they are not from the main royal family, they are still treated and are part of the royalty, since in this kingdom 'royalty' is a class related to royal ancestry, so whoever has royal blood (golden eyes) is technically considerated to be royalty. Idk if that was your question but I hope it made sense. Basically, all royals have royal ancestry but they are not all so close related since they come from a long lineage of almost one thousand years of history.
