Second Sun of Solaria

The Second Sun of Solaria is a star introduced in Season 5.

Overview
The Second Sun of Solaria is one of the three magic stars of the Magic Dimension that function as Solaria's suns and provides light to many realms, and is therefore its planet's source of life without which Solaria is destined for darkness. The king of Solaria cannot live without both of its planet's suns. While the three Suns of Solaria are located in space and can be seen in Solaria's skies at day, the essence of both the First and Second Sun of Solaria are housed in the Steeple of the Sun inside the Royal Palace of Solaria. The alignment of the three Suns of Solaria is a rare occurrence and it is a cause of celebration for the citizens of Solaria.

The King or Queen of Solaria can command the Second Sun of Solaria to send its light to other realms, as seen when Luna asked it to send its light to Earth to help the alliance against Tritannus.

Appearance
The Second Sun of Solaria yellow star. Its power stored in the Steeple of the Sun is an orange ball of light that occasionally has specks of red and yellow.

Season 5
In "The Pillar of Light," Luna enters the Steeple of the Sun in a panic as the light of the Sun of Solaria is eclipsed. Finding Radius, she asks him if he is alright, but he is displeased that she did not knock. She expresses her concern for him due to the strange darkness plaguing Solaria, but he assures her that the Second Sun of Solaria will compensate for it. Luna once again voices her concerns, but Radius rejects her. Just then, the sun shines blindingly and begins to flicker, weakening Radius as Luna screams out for help. Later, Luna tells Stella about Radius' condition and that the darkness has affected both the suns of Solaria, and that the king cannot live without them. In "The Eclipse," the Second Sun of Solaria shines again in the Steeple of the Sun as the eclipse of the Sun of Solaria ends.

In "Saving Paradise Bay," the two suns are in the sky of Solaria as Luna intercedes for the alliance against Tritannus, asking the Second Sun of Solaria to shine for the alliance, and through her, send its light to them. Meanwhile, the light of the second sun strengthens the alliance.

Season 6
In "Queen for a Day," on Solaria, the citizens celebrate the rare occurrence when all three suns of Solaria align in the sky.
