Shop Atmosphere

“The shop constantly ticks: gears on display rotate, an idle automaton cat winds itself and strolls around the shelves. The bell over the door is a tiny gong rigged to a spring; when customers haggle, Brennix may add in a free repair or a dubious invention as a test. Brennix accepts gold, electrum, silver and copper but loves swapping schematics and rare components for discounts. He will refuse to sell any schematics to anyone who cannot name the inventor who inspired them.”
