Milo Vanderbeck, also known as "Rusty", was a halfling and Shani's mentor and friend. She worked beside him in the field hospital during the Battle of Brenna, alongside Marti Södergren and Iola the Second.
In The Witcher computer game
Shani refers to him in quite a good number of the conversations Geralt has with her. She even mentions his death to Geralt. He is also mentioned, not by name, by one of the nurses at St. Lebioda's Hospital. Both she and Shani quote Rusty as saying "Stitch red to red and white to white and everything will be alright".
In the Enhanced Edition of the game, this little mantra was augmented to "Stitch red to red, grey to grey and white to white and everything will be alright".
He is the author of a book entitled "The Rudiments of Pathomorphology".
