Her name is well deserved, as she’s the daughter of Insanity and Fear.
Macu spends his time looking for kind and giving people who he rewards in some small way. He does this by disguising himself as a needy person, maybe an injured traveler on the road, or a beggar in a town. The first person that responds kindly to him will receive some assistance in the endeavors, they will find out about the assistance when Macu has finished helping them. If a party member is simply indifferent to Macu then Macu will give the party another chance, in a different situation, if the party is still indifferent then he will leave them alone without interfering with them anymore. If the party is cruel or evil in anyway to Macu then he will punish them is some suitable way that matches their evilness. He will even show himself to them so that they will recognize him and the fact that they were evil/cruel to him.
While travelling near the edge of a forest the air is filled with the wailing of battle horns. Soon a large group of mounted cavalry will gallop by in a panicked rush. Some will spot the party and shout "Flee! Flee for your very lives!"
Several minutes later, hundreds of running infantrymen will be spotted. A large group of white clad knights fiercely chanting a battle song is in full pursuit. One of the white knights carries a banner of a white horse on a black background. The horse is rearing under a gold crown, indicating the presence of the Paladin Prince. As the horrified infantrymen struggle to flee into the forest, the zealots charge into their midst and cut them down by the tens and hundreds.
