A man from Legends was the Humans Lanoree and Dalien Brock's grandparent. This man gifted a blaster pistol to his grandson, Dalien, when he was still young, before his death. Dalien would use this pistol for the remainder of his life, including to rescue himself and his sister from a silik lizard.
The Legends novel Dawn of the Jedi: Into the Void, by Tim Lebbon, first referenced Lanoree Brock's grandfather. He was originally identified as the previous owner of Dalien Brock's blaster pistol.
