It all started when Nienke met Sarah,and told her that there is a treasure in the house,and gave her a locket.Mainly,Fabian,Nienke and Amber solves riddles,do "Midtime" activities to find and protect the treasure.Fabian always reads the clues that contains Hieroglyphics,Nienke and Amber does the sneaking job.In season 1,they need to find the graal. Their enemies at this point were the Anubis Association,which the leader was Victor Emanuel Rodenmaar Jr. At first, Nienke was on her own to find the very first riddle (which is in the back of Sarah's portrait).Because of Patricia's suspicion to her,she steals the riddle.But,Fabian sees this and gives the riddle back to Nienke.They also found clues in a treasure chest (on attic) which contains wax rolls, that has recordings of Sarah.Fabian founds out that Victor was also finding the graal for eternal life,because he seen Victor making an elixir and talks to Corvus about the graal. Another clue,was on the grandfather clock,which Victor sees broken,and tries to find out who broke the clock.Then Appie,got his CSI kit, and when Victor sees this,he let Appie investigate the clock,exchange for a dracula coffin.He finds fingerprints in the glass of the clock but he doesn't know who has that fingerprint.By that,he gets all fingerprints of residents to find out who really broke the clock.Then,he overheards Nienke talking to Fabian and Amber about the riddle of the clock,which Appie forcefully entered and ask if what they're hiding,or he'll expose to Jeroen and the others that the fingerprints were from Nienke and Fabian.Because of that,they told Appie the truth, and now, part of the group.Patricia joined the group when she knew about the real reason of the dissapearance of Joyce,and when she was kidnapped.She begs forgiveness to Nienke for all that she's done and was forgiven, and now part of the club.In season 2,the mystery revolves about the Chosen One.Then, a new character appear,which is Noa van Rijn (because Mara left for Dubai).Actually,she was the Chosen One,considering she was an Egyptian princess and a descendant of Amneris.But also,new enemies appear,which is Wolf Rensen. he is the new history teacher, which is a replacement for Jason. One of the clues involve the hieroglyphics symbol blocks. In Season 4, they need to protect the tear of Isis, also protect the chosen one. because Nienke had a vision that Noa is lying in a bed dying.
