Adrian Ivashkov is a Moroi of royal blood, a member of the 12 royal Moroi families present in the VA-verse. He is the only great-nephew of the current reigning Queen, Tatiana Ivashkov. The only other family members mentioned in the books are his father (Nathan) and one of his grandmothers.
All Moroi have magic, some being stronger than others. All of them are quite good at compulsion, particularly inflicted on human beings. Therefore, they can persuade people to do their bidding. Each Moroi specializes sooner or later in one of the four elements (Air, Earth, Fire, Water); some, however, like Adrian, his 'cousin' Vasilisa Dragomir or a woman named Oksana, never do. They work with spirit instead.
Wielding spirit-magic gives Adrian the ability to walk in people's dreams and communicate with them in this way. His compulsion is extremely strong, and he also trained with his 'cousin' in the arts of healing. He didn't get very far with that.
Spirit magic has devastating effects on a Moroi's inner self. Adrian is a heavy drinker and a chain-smoker, trying to counterpart the price his soul has to pay each time when he uses his magic. Therefore, he is often subject to moods, odd behaviour, or self-destructive tendencies.
Adrian is tall and lean (6'2 - 6'4); all Moroi are generally slender and quite pale. His eyes are deep-green and his hair is brown, usually described as 'styled so that it looks messy'.
His wardrobe is expensive; usually he sports designer shirts and jeans. His signature are the clove-scented cigarettes he's always smoking.
Adrian Ivashkov is a man - well, Moroi - you can trust. He's a people's person, always enjoying their company, always at the ready with an ironic comment. Beyond the cool, aloof facade, however, hides a sensible spirit and a heart of gold.
He's genuinely concerned for his friends and strives to prove himself in their eyes [i.e. he has a protective nature of younger students which shows a semi responsible side at times
He's not an adept of physical fights, his greatest weapon is the spoken word
