Kalatar

Kathrandir 'Kalatar' Vanyarin, later known as The Black Dragon and the Aspect of Death. He was the Emperor of the Vanyarin Empire and second patriarch of the Vanyarin crest, only to be succeded by the Witch-King Qetharyn 'Jayran' Vanyarin.

He was the younger brother of King Celebrenor Vanyarin and turned against his brother after his wife was killed by disease that injured the land, without his brother's care on the matter the hatred grew. Kalatar always fell in his brother's shadow and seeked to become greater.

Kalatar turned to necromancy and the arts of black magic and later discovered his "gift", the mark of the black dragon which would allow him to transform into a firebreathing giant dragon with enough power.

During a raid on Krayta, Kalatar decided to turn his back on his King and brother, overthrowing him and then setting loose hell over Krayta, destroying the entire city to ash and ruin. Kalatar destroyed Celebrenor's crown and executed Celebrenor's wife when she sent away their son, Qetharyn.

Early Life
Not much is known of Kalatar's early life, only that he was a direct offspring of the Qendaryan god, Vanyar, so to say if you believe in mythology. He was the second child, the younger brother of King Celebrenor Vanyarin. They built the kingdom of Qendaya together and Kalatar was responsible for the construction of the city lower grounds and sewers, it was believed that he'd build secret pathways under the city, and perhaps even a city under the city...

Kathrandir the Betrayer
During a raid Kalatar betrayed his brother and destroyed his crown, killing all of his loyalists he claimed leadership over the Qendaryan domain, but it was all in ash.

Hunt for Qetharyn Vanyarin
Before the death of Queen Aryanne, she managed to free her son Qetharyn and give him an escape route, he was but an infant and Kalatar sent out hunters and assassins to locate the baby boy but never found him. Assuming he was dead, Kalatar continued his plans.

Rise of the Vanyarin Empire
“''You were my greatest student. It should've been you, standing by my side destroying our enemies. I offered you a home, I gave you your heritage, trained you as my own. I will honor you with a quick death.''”
 * — Kalatar lexuring Qetharyn before his defeat.

Years past and Kalatar has been spending time building up his army of darkness, his secret Empire inside the ruins of Krayta.

When Qetharyn came to Krayta, searching for his heritage and home, Kalatar made illusions and disguised himself as an elderly man, training Qetharyn in the arts of Vanyarin fighting and magic, skills difficult to learn. Without suspicion, Kalatar helped Qetharyn until Qetharyn unveiled some of the illusions, Qetharyn confronted Kalatar and they fought and then Kalatar dissapeared.

Kalatar lurked in the shadows, while Qetharyn ruled the Vanyarins for the first time, Kalatar turned Qetharyn's people against him, leaving Qetharyn alone with Sirtum Crow at his side.

Preparing his Empire, he set out across the galaxy, destroying innocent worlds to gather their core of souls. Eventually ultimately defeated by Qetharyn himself and overthrown as leader of the Vanyarin Empire.

Return & Cataclysm
“''Pain... Agony... My hatred burns through the cavernous deeps. The world heaves with my torment. Its wretched kingdoms quake beneath my rage. But at last... The whole galaxy will break... And all will burn beneath the shadow of my wings.''” The Cataclysm is the total destruction of all living things, as Kalatar had planned for centuries, he had finally gained the strength in the shadows to build up a giant army of dragons and became the leader of the dragons, as the Black Dragon, the Dragon of Death.
 * — Kalatar causing the Cataclysm

Succeding in destroying half the galaxy in the main universe and making most planets into hellscapes, the heroes of the galaxy made one last stand against Kalatar and his dragons, and while doing so the heroes opened up multiple versions of the universe to gain knowledge and artifacts that could defeat the black dragon.

In the Endgame battle, the final battle, all heroes stood as one, all of the people of the families and factions against Kalatar's army and used their artifacts against him.

Qetharyn Vanyarin, then known only as Jayran, defeated Kalatar in battle by sacrificing himself to destroy the black dragon which then destroyed Kalatar's fleets and armies, the life of all dragons were drained.
