Migos rapper Quavo mourned the loss of his nephew and bandmate, Takeoff , with a heartfelt tribute he posted on Instagram Saturday.

The rapper reflected on the memories they shared while growing up together, in a lengthy letter he dedicated to the slain artist. Takeoff, whose real name was Kirsnick Khari Ball, was with Quavo when he was shot and killed outside a bowling alley in the early morning hours on Nov. 1. He was 28 years old.

Super quiet though, quietest in the room, but paid attention to everything going on in the room, always been like that!!! Quavo wrote. Nothing ever really bothered Take and he didnt bother anybody. He the most unbothered person in the world.

The letter continued: He never got mad, he never raised his voice, and when he did, he silenced the room because what Take said was law.

Quavo, 31, later talked about his relationship with Takeoff, and how he previously couldnt find the right title to describe their tight bond since uncle didnt feel close enough.

Now I finally get it... you are OUR angel, he said. (Read his full letter here .)
