I made him just for Asra.
He lived in Vesuvia his whole life, his shop is a family heritage. When he was in his late teens, he helped Asra and Muriel when they fled from Lucio's grasp.
He and his family keep them hidden in the shop and help them find places of their own.
Klaus is used to be ostracized because of his appearance. His family has a singular lineage connected with the underworld (gift of long, long lost generations pacts with fiends) that makes every once in a while a child be born with fiend characteristics. His body is warmer than humans, he can smell things better and see better in the dark.
Because of his appearance, he always got mugged when he was alone in the streets, so he learned how to fend for himself even without the use of magic. He is a very good fighter and knows how to play dirty.
He is very tall, so people stopped bothering him so much when he got older. Seeing him as intimidating, even if he has never done anything to show that he that dangerous.
When you get to know him, he is very kind and compassionate. Very lawful and steady mind. He doesn't mind teaching you his tricks to fist fight and will surely defend you if you don't mess with him.
He can curl his tail on you if he likes you. It will wiggle on its own when he is feeling strong emotions. It doesn't have enough strength to use as a weapon, but he can hit you with it. It just going to sting a bit.
Like Asra, he is very sassy and likes to play mysteriously. They basically grew up together, although their relationship wouldn't blossom until very late in their life. They trained magic together, researched new magics together, went to every Masquerade together to mess things for Lucio.
To some, it may look like he is charming and playful, but he is not. He just like to act that way. He is very lonely in his personal life, he never had anyone that he could fall in love like everyone around him had. So when things with Asra took a step towards this seriously, he got a feeling of relief, peace and belonging.
When the plague came, Klaus couldn't and wouldn't leave his home city to die. He work his way to give people what they need, to get medicine from other cities and even contraband stuff for the plague doctors to work with.
He has a bunny, Roxxie, as his familiar. Asra took care of her when he was gone.
