Shopkeepers are generally categorized according to their occupation - which can be observed from the type of establishment they are present in. The overarching titles "shopkeepers" and "merchants" can be found in the NPC scripts. The individual titles "tavern keeper", "blacksmith" and "butcher" can also be found in the NPC script, with the Silicon Knights FAQ also mentioning "Butchers" and "Barkeeps". The official strategy guide and Crystal Dynamics guide both offer "bartender" as an alternative for the latter. Developer assisted magazine previews also attest to the "blacksmith" title.[1] Other internal classifications list "Barkeep", "Blacksmith" and "Lupo" - with the latter linking the title to the Lupo character and suggesting it may have been a generic title for all butchers.
