The royal family assembled to the great hall where Adrian and his companions were guided. The royal family of the Kingdom of Suburiasi looked healthy but Adrian could see a deep looming grudge attached to them. The curse is definitely of divine nature which meant that even holy magic will not be able to purify it.
The members of the royal family are currently the retired king, the current king and queen, the crown prince, the first and second prince, and the third prince that is currently in a mobile cradle. Adrian could not see any brother or sister of the king which meant two things.
The brothers or sisters of the king are either away or dead. If the other royal family members of other kingdoms know of the curse, then they will not accept marriage proposals from this family. Actually, Adrian is already impressed that the queen managed to give birth to three sons.
