Urrezko Kaiola is an ARG centering around an RPG game called Urrezko Kaiola Terminal. Every character within is sentient and can communicate with players directly. Several have twitter accounts, a few have Discord accounts, and one even runs the subreddit (/r/urrezkokaiola). After completing Chapter Zero (past the trailhead) players gain access to the Discord server, which also grants users access to each consecutive chapter of the game as they complete them.
