Trial of the Oracle Arc

The Trial of the Oracle is one of the story arcs of the series.
== Synopsis ==
The members of the Congregation were questioning the Oracle's recent actions, and he shocked everyone by putting himself on trial. 
The Guardians are called in to recall his recent unsatisfactory deeds and he was later found guilty by Endarno and was banished back into his home world, Basilíade.
Back home in Heatherfield, Will confronted Orube and Matt, while Principal Knickerbocker went to drastic measures to raise the girls' grades at Sheffield Institute. 
In Kandrakar, the Council elected Endarno the new Oracle.
After Endarno has been chosen, he made the life of the Guardians difficult by trying to prove to the Congregation that they are too young and immature. 
He also convinced the Congregation that Elyon, the queen and the Light of Meridian, was dangerous and unfit to rule over Meridian.
Endarno tried to get the Guardians to arrest their old friend and bring him the Crown of Light, but W.I.Z.A.R.D. managed to hide Elyon from him by smuggling her back to Earth and had Orube protect her. 
Moreover, Endarno is someone other than he appears to be... an old enemy coming back for revenge and a bigger thirst for power. 
Elyon and Yan Lin discovered that Endarno is actually Nerissa who had been using Endarno's body in her new quest for power and revenge.
Orube went to Basiliade in order to find the previous Oracle, now living under his old name, Himerish. 
Together, they returned to Earth to meet with the Guardians and they tried to free Elyon from her prison and put a stop to Nerissa, still disguised as Endarno, was formally instated as the Oracle.
Himerish was able to locate the real Endarno and he, in turn, revealed to the Council that the Endarno that they knew was Nerissa in her body. 
Elyon returned to power on her world, and Nerissa, rather than being locked up in the jewel again, threw herself into the endless void of Kandrakar.
