Enemies of Greed. Mercenary behavior offends the sensibilities of astri, but they understand many people have strong selfish streaks. Astri counter this selfishness by magically enforcing the desire to help others. Before an astri assists an intelligent creature, it asks the creature to promise to do good deeds over the next few weeks. If a creature won't make the promise, the astri still assists, but the creature must contend with the geas that may be attached to the helping hand.
