With magic all but lost, mage guilds are few and far between. The Sleeping Dragon guild, a lingering relic of the past, continues to operate any way it can. So long as the price is right, the talented individuals of this guild can handle any mission thrown their way, legal or otherwise.   As a courier for the Sleeping Dragon Guild, Cross prefers things simple. He keeps to a tight (albeit rather lazy) schedule and does his best not to deviate from it. But things do not always go according to plan. When he crosses path with a young girl claiming to be a Spirit Goddess, he and his fellow guildmates are pulled into a dark scheme over a century in the making.
