Xanthe has lived in Phos Astos underground her whole life, she is very proud everything her city has built out of fungi and large mushrooms. Her city and all the other cities have built thousands of tunnels going all over the world, she also knows the tunnel way to The Evertree by heart. After she leads Takoda, Meilin, and Conor across the musical web, they are forced into the Sulfur Sea when Kovo slides into them-except for Xanthe, who is assumed to have disappeared.
In The Books
Xanthe appears shortly after The Many attack Meilin and she rescues Meilin, Conor, and Takoda from being killed and brings them to the tunnel way on to Phos Astos. She tells them about Sadre and its pathways. She then shows them around Phos Astos and introduces them to the Elders who explain their history, The Many, and the Wyrm to them. When the Many infiltrate Phos Astos, Ingailor is killed after he saves Xanthe's life. At the end of the book Xanthe, Conor, Meilin and Takoda start on their way to kill the Wyrm and save the Evertree.
Xanthe, Meilin, Conor, and Takoda continue to travel through Sadre. She guides them to a place where the cave splits into two paths. Although they originally try to take the left path, it is filled with the Many, and they have to return to the split, and take the right path (which is much more difficult to take than the left one), where they must pass three "trials." She tells them of the first two: the Archane Fields and the Sulfur Sea, but does not explain the third.While the group attempts to cross the Archane Fields, Xanthe is separated from Conor, Meilin, and Takoda, leaving them without a guide in the Sulfur Sea.
The Burning Tide
Xanthe appears, near the end of the book, with an army of Sadreans to assist Meilin and Takoda in holding off the Many. Xanthe briefly recollects how she survived after being separated from the group, having made it almost entirely because of her determination to save Takoda.
When the Wyrm hatches and grabs Takoda, she attempts to help him, although Kovo beats her to it. Meilin asks her for help ringing the bell (as she cannot lift the mallet on her own). Xanthe does so, and together they ring the bell (although the snare is jammed), opening the portal to Erdas for the Wyrm.
Abeke mentions in the epilogue that Xanthe and Takoda came out of the doorway holding hands.
Takoda and Xanthe become good friends throughout Immortal Guardians. Takoda accidentally bumps into her when they are travelling to Phos Astos, and Xanthe blushes. There is a tiny bit of evidence that they may like each other, this is most likely due to the fact that the Sadreans admire Kovo (who is bonded to Takoda).
