Pirlor

Pirlor, The Former Queen of Glacialis. 

Pirlor was Niveis's Sister and became queen before he became king because he stepped out of line to be with his friend, Aqua. Niveis eventually joined the Military and became head General, and Pirlor's most trusted soldier.

After Niveis Left, The military fell into disarray, and as her mind became clouded with power and corruption, she could not pick a new general because of trust issues. 

But eventually, she had a mate, Icerio, and she appointed him as Head General after their egg hatched, whom they named Cerio. After Icerio returned from a station in the far reaches of Glacialis, he came back with the Rare disease known as "Septicemic's Triumph" Which was a bacteria that silently spread through the body, and then attacked the Nervous system all at once.  

Thankfully this disease is only contracted through a rare type of bird that carries it naturally and is not contagious, or the whole kingdom might have been at risk. 

This made Pirlor go practically mad. 

She was deemed unfit to care for Cerio and he was sent off to the Northern Kingdom. Pirlor did not seem to care at that point, although many could tell this saddened her more. 

She flooded the cities of Glacialis with guards so nobody would even try to kill her in her emotionally weak state, and to show that she was still powerful.

One day her brother returned, but with a strange dragon. 

Niveis came asking if they could have the help of her army. Pirlor was then insulted by the strange dragon, Eclipse, and mocked. Eclipse then proceeded to slash his talons across her face. Racked with pain and her mind scrambled, she Roared for her guards to attack Eclipse and Her brother. 

They flew away off into the horizon. 

A few days pass, and Pirlor tracks her brother's sent, with a bag of potions slung around her side and a dagger tied to her leg. 

she disguises herself as Glacies, their mother, and encounters Eclipse. 

She tries to trick him into leading him into leading her to Niveis, but it fails and she is found out.

she quickly gulps down a perception potion and disappears. 

She uses her powerful sense of smell to track her brother down to the Night Kingdom Castle, where she finds him alone in the dining hall, She slits his throat, and he falls to the floor, blood pouring out of his neck.
She laughs Triumphantly as Eclipse barges in. 

Eclipse kills her, and brings Niveis back to life. 

Her body is tossed into the sea.

(Eclipse, The Night Kingdom, and the continent that Niveis and Eclipse traveled to, Belong to The Great Lagi)
