Srek is the local blacksmith and armorer of the The Patched Kettle in Cratenga. Though she doesn't give of the impression of being able to hammer metal into shapes, she seems to produce decent and sturdy gear (though often with a somewhat unnecessary darker theme). She also has a firm understanding of how to use her products, which makes her not to be underestimated.
 
She and Drekken no love for each other, with her shop being one of the few not owned partially by him and her fighting experience scaring of most of his goons.
 
She apparently has a sister working as a clothier in Pelesta.
 
Aside from the more common weapons and armour, she sells some decent goblin improved gear.
