The Saga of Blood and Gold
From the outside it seems to be a perfectly normal shop (albeit one with an unsettling name) but upon entering customers are usually quite unnerved. There is very little light beyond a few candles and jars of burning incense. The shop is almost a shrine to the weapons produced inside it.
The owner, Laurian Naïlo is similarly disturbing, treating all customers as if they share his passion for long-ranged killing. This scares off the majority of potential customers, but those who stay will be offered an array of weaponry unlike anything they have ever seen!
