- Not to be confused with Baron Silverlaine.
Silverlaine Thorne is the younger brother of Greydon Thorne. Approximately 4 years after the Second War, the two brothers arrived to Gadgetzan in Tanaris and visited a newly-opened bookstore owned by the goblin Charnas. Greydon and Charnas began conversing, but Silverlaine wasn't interested in that, so he left them alone.
20 years later, Greydon's son Aramar Thorne coincidentally met Charnas who revealed him the existence of Silverlaine. The goblin told him that Greydon had been very proud of Silverlaine, but that he only met Silverlaine once, so he wasn't sure what happened to him. Charnas knew that Greydon didn't mention him much, but when Charnas did ask about Silverlaine, Captain Thorne said that they hadn't seem each other recently.
