First appeared in the Season 2 episode "Q is for Quarry". It was created when Kadma stole the Heart of Meridian and merged it with the Heart of Zamballa after Will refused to absorb the Heart of Meridian. However, as the Heart of Meridian was stolen rather than given away, the Heart returned to Nerissa, who called the combined Heart, the Seal of Nerissa. In "U is for Undivided", Nerissa tries and adds Lillian's Heart of Earth to her Seal but fails. In "V is for Victory", Will discovers that they can't take the Seal because of the Heart of Meridian was given to Nerissa freely, so she frees Phobos since he can take it and bend the rule.
Nerissa then absorbs the original Guardians into the Seal after they snapped out of her control. This allowed the Seal to have all the Guardians' powers. Phobos managed to gain the Seal away from Nerissa, and renames it the Sceptre of Phobos. After retaking Meridian, Phobos sets his sights on Kandrakar, and is on the verge of taking it when he is betrayed by Lord Cedric, who swallows him whole, thus gaining his powers for his own. After Cedric's defeat, Phobos is brought back up and the Seal is also broken, separating into a tear-drop jewel and the Heart of Zamballa. C.H.Y.K.N. and Elyon manage to escape, however, Nerissa can't since she doesn't have harmony.
The Seal of Nerissa was stolen by Phobos in "W is for Witch" and it was later temporarily renamed the "Scepter of Phobos" in "X is for Xanadu".
