Angelic Guide
Aasimar are inherently linked to an angelic being. They call upon this "guide" to understand the world around them, and help inform their decisions through emotions and senses. They are far from omniscient, and is up to your DM as to how involved they are in your play - sometimes providing vague help all the way to specific role-playing opportunities, and plot hooks.
In Volo's Guide to Monsters, there is a list of Angelic Guides that you may choose from, or you may work with the DM to name and create your own.
