Meet my Rogue/Sorcerer Tiefling, Kira! Level 9 in both classes (a feature my DM granted the campaign), she's an ex-prisoner (falsely accused) who's on a work release program from the prison to work off the rest of her sentence under the guidance of a mentor, Ezreal, who's another player in the campaign. The tattoos all over her body are arcane leylines and runic focuses to help her direct the flow of magic in her body, allowing her to use momentum and movement from her body as replacement for normal hand sign somatic components.

Kira is also unable to see the weave the way other spellcasters can. Instead of seeing the threads of mana that make up spells before they're formed, or run through enchantments, she instead can hear them... though she can still see the effects they produce!
(For example, she can't see the threads of evocation that a wizard weaves in their fingers, but she can see the fireball it produces when it's launched at her)

This picture is specifically Kira after she obtained several new magic items - she originally had the knife in her hand, which allowed her to teleport where it was thrown, but in the most recent session she also achieved:
A set of armor that allowed her to cast Fog Cloud, and see through/teleport inside of opaque fog or mist
A half-cape (hard to see but on her right side) that allows her to mimic spells her allies cast
and a knife (the floating one) that allows her to make an extra attack, as well as reduces ranged damage.
The staff isn't technically canon yet, but I plan on picking one up in the future, so I added it since it looked cool!
