This is Ominis Gaunt and Insidious Gaunt. They’re twin brothers and both direct descendants of Salazar Slytherin. Both wizards can also speak parseltongue and are very skilled magic users. While Ominis tends to keep to himself, Insidious is more outgoing. Insidious is also a huge flirt compared to Ominis, but Ominis is pretty open once he gets to know you more. Both twins are very dedicated and loyal to each other as well, while Insidious isn’t as resistant to using the dark arts as Ominis is. Ominis was also born blind and uses his nearly-sentient wand to help him navigate.
