Walter is the Squire to Ser Baris Kellington from the Stormlands. He came to be Ser Baris's squire more through his family's financial influence than any other means. Youngest son to a wealthy merchant, Walter would most definitely not inherit the family business. The boy was often left to his own devices while growing up and so when he finally asked his father if he could travel the world and learn the ways of the sword, the old man quickly complied. Through a trade agreement only known between the boy's father and Ser Baris Kellington, Walter was transferred to the Ser's tutelage. As a parting gift, the merchant bestowed upon the Ser a chest to give the boy when the Ser deemed him ready. It has been several months since then and Walter has proved a most apt learner, quickly taking to the tasks set him by the knight.

 With upcoming Tourney, Ser Baris had sent the young man to Black Haven while the knight prepared in King's Landing. Without Walter's knowledge, Ser Baris was having the contents of the chest fitted for the boy. Inside the chest was a set of armor along with some coin for the sir to have it altered to fit the lad, and to acquire the necessary weapons that the Ser felt the boy need have. In fact it was his intention to surprise Walter, and bestow it upon the lad at the tourney so that he might compete and ascend to knighthood.
