I just thought of another one.
My uber healer cleric eventually takes Spirit Talker and then Mending Spirit. Part of his back-story is that he was once a lowly grunt soldier in a large-scale war against goblinoids. Because of the horrors he witnessed and losing all his buddies, he lost faith in the gods.
He became a begger on the streets and got beaten up one night. A kindly cleric brought him to his temple and mended his wounds, both physical and psychological. As payment, he worked in the temple for several years doing menial tasks and was content.
He was asked to accompany the cleric on a journey to another town. They were accosted by bandits and despite surrendering and handing over their valuables, the bandits killed the clerics anyway. The character cursed the gods and claimed they were heartless bastards and lashed out at the bandit leader.
This manifested his own clerical power and smote the bandit leader. An angel of the cleric's god descended and took the cleric's soul, and the character could see it. The angel spoke to him and told him he had a path to follow, and that he was meant to combat the evils of the world and alleviate the suffering of the innocent against the tyrannical.
So now he has the Dragon Coast benefit to gain Supernal (speaks with angels that nobody else can see, so he seems like a crazy old man). And once he gains Spirit Talker, his Spirit Companion is actually an angel that manifests so that everyone can see it, finally justifying all that crazy talk
