Participating in the "Howlion's Trial" and "Unfinished Scroll" gameplay earns you "Clear Heart" and "Ink Charm," which can be used to light up and leave your mark in the Radiant Horizons. Zooming in on the golden river area at the bottom to the maximum allows you to pick a desired location within each phase's open area to light up the Radiant Horizons. When the server-wide light-up count reaches a certain threshold, the next phase will unlock.
