Story Time Achievement
Participate in 60 Kefling's stories
"Stories" in this sense really means quests. Quests are available from any NPC that has a yellow explanation mark over their heads. Simply talk to them and complete the quest in order to complete the "story". There are a little over 60 total quests, so you will have to do most of them in order to get this, so take your time and help out anyone who needs help.
