Vrus Renex

His Background
He has blood of the original Red Dragon (Another name of it is ルビードラゴン) in his DNA and his Necklace. The Necklace was given from Obsidian and from his father Eragon. How this necklace works is by it given to someone who seems worthy to the necklace holder. The necklace has the blood of the original Red Dragon which gives unbelievable power (example: the power of Water Manipulation, Earth Manipulation, and Air Manipulation). With the blood of the Red Dragon in the necklace whoever isn't worthy or a necklace user and whoever doesn’t fit that category gets thrown away.

Vrus's Backstory
He was originally trained with his father Eragon. He despised his father his his horrible treatment so when time came he went to Obsidian for Vrus to soon find out she was his mother. With his father he was forced to kill 5 dragons they were the Garnet, Topaz, Emerald, Sapphire, and Amethyst Dragons. He was also forced to kill them in Dragon's Wrath Stage 4

With old Vrus he was kind until he claims his eyes widen and he started to be moody. After his memory got erased for the 2nd time he has a energetic, kind, and trustworthy personality, until Claire got corrupted (again) he his just being kind especially to Lyra to not make her worry.
