Dark Mode (BETA):

Dunno if you still need help, probably not. But for those who still wonder, here’s how. Contribution points (CP) are gained with certain quests. Often are that quests on farms, such as loggia farm and trade quests as well. Trade quests are found at trade managers, which are found in towns and cities and the western guard camp (first place you come across when leaving olvia for the first time)
