I remember her most for helping us with communication.
Think of her trumpet as a reminder of her getting the word out to the crowds. Whenever I need/want a message to get out into the world and be heard, I ask her to help spread it around like peanut butter.
I’ve heard her referred to as the “Messenger Angel”. She helps bring us crystal clear messages from the Divine. She helps get our message out crystal clear to those who need it.
