Lorithia

Lorithia is an antagonist in Xenoblade Chronicles. She is the leader of the High Entia's Ministry of Research; as such, she mostly operates by designing new technologies and weapons for her people. She is actually one of Zanza's disciple and has such she has been granted eternal life and huge powers. She also has something of a rivalry with Dickson, but nonetheless tolerates him for his knowledge and abilities.

Before the events of Xenoblade Chronicles
She joined the trinity long before the events of the game and started to manipuled the High Entia imperial family to advance Zanza's own agenda.

As the Minister of Research
Lorithia is introduced soon after entering the upper Bionis, where she is shown to be creating Telethia. She talks with Yumea and Tyrea, sympathising with her on the fact that Melia is in line for the throne in spite of being half-Homs.

She then escorts Melia to the High Entia Tomb for her trial, but does not take a highly active role in the story until Prince Kallian start to gather the allied forces in order to fight Mechonis following the events at Prison Island.

In the time leading up to the battle, she begins researching the Ether-damaging green fluids in the Mechon spear used to kill Arglas's body on Prison Island. She is joined in this by Alvis. As a countermeasure to the fluid, she designs the Havres: aircrafts that the allied forces will use at the second battle at Sword Valley. She is present at the battle, but hangs back from the combat to watch as the allied force fights knowing what is going to happen.

As Zanza's Disciple
After the events at the Mechonis Core, the Havres squadren led by herself and Kallian comes to the party's aid during Dickson's Telethia assault on Junks. She is then revealed to be one of Zanza's three disciples, and taunts Kallian for not having realised this before, she then releasing vast amounts of ether from the aircraft to transform the other High Entia into Telethia. In the process of his transformation, Kallian is ordered to kill Melia but his will, alongside support from Melia, leads to his resistance to obey and he turns on Lorithia and Dickson instead.

She is then revealed to be alive when the party meet her in the Bionis' Interior. She invite the group to follow her into the heart of the Bionis where she fuse with Kallian and engage the party in a fight where she is killed.
