S4 Ep21-Royal Siblings
#23 of The heroes of Gaia (season 4)
It seems that the siblings of the guardians had began looking for them but with not a very successful way.
The heroes of Gaia have been missing for one full week; they have not been spotted on earth or anything; the remaining members of the moonstone family have started to search for Artemis and Solaris. Celeste and Luna had checked out their temple which was empty and untouched, King Moonstone put himself in the leadership position as again the other kingdoms needed to work together to find them. The people on gaia are also behind the monarchs of their respective kingdoms and actively search for the missing princes along with Justin as well. But no one knew the true danger that they were in on Saikou island.
