The Brentaal Trading Houses, which can also be referred to as Brentaal trading houses, were situated on the Core Worlds planet of Brentaal IV. The Master Codebreaker, seeking a respite from deciphering and looking to gain credits, traveled to these trading houses on Brentaal. Brentaal was among the dwindling number of worlds where the Codebreaker was still permitted to engage in games of chance, the details of which he documented in the Smuggler's Guide. The smuggler named Platt Okeefe cited the Trading Houses in the Smuggler's Guide as a place to obtain aurodium for smuggling purposes.
