AURORA
Sparrow's Guild
Aurora is the badge, attendance, and marketplace system of Sparrow's Guild. Collect CES Badges at every workshop, stamp your way through OSO Day with the Explorer Pass, and race toward the Fast-Pass achievement.
Each program rewards a different way of showing up — attending, buying, exploring, and thinking.
Every membership, workshop, and CES-related event you attend earns a sticker badge. Stack enough badges and unlock the Fast-Pass achievement for priority entry to limited-slot events.
Attendance RewardAvailable only during OSO Membership Day & Marketplace. Every product purchase earns a half-value mini badge — buy twice, complete one full CES Badge, and step closer to Fast-Pass.
Marketplace RewardTurn OSO Day into an expedition. Instead of one sign-in, collect stamps at every booth, workshop, and activity you visit — a living record of how you explored the guild.
OSO Day AttendanceBefore you buy, you can play. Write true or false, draw your guess on the box — match it and the item is free. Miss it and you buy at full price. Logic has stakes.
Merch GameBadges render as light — a gradient that runs from Aurora blue to sparrow gold.

Fast-PassBefore checkout, the system generates a two-variable logic statement. You write your predicted truth value, then draw a card. If your prediction matches the evaluated statement, the product is yours — free. If it doesn't, you pay the listed price. Every round is generated and verified server-side, so no one can rig the draw.
Track your CES Badges, Explorer Pass stamps, digital ID, and Fast-Pass progress.
