AURORASparrow'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. Predict true or false on an actual two-variable logic table — match the evaluated row and the item is free. Miss it and you buy at full price.
Merch GameBadges render as light — a gradient that runs across the current theme's palette.

Fast-PassBefore checkout, the system generates a two-variable logic statement and shows the full mathematical truth table. You predict true or false, then the target row is revealed. Match it and the item you chose is yours — free. Miss it and 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.
