Diana would be a blue iris, and there are a couple reasons for this. Irises get their name from the Greek goddess Iris, who was said to act as messenger between the Greek pantheon and humans, and as Selûne's Chosen, Diana sometimes gets to serve as a messenger herself. But beyond that, blue irises in particular are a symbol of faith and hope. Diana's faith is the foundation of who she is as a person, and she's able to find a silver lining in almost any situation.
Blue irises are also a sign of deep trust, and Diana is trustworthy herself, but she also puts deep trust in the people she cares about because she expects them to be trustworthy, too. Let's just say this expectation does not always serve her well.
But yes. Diana would be a blue iris.
No-pressure tagging @bardic-inspo, @vividiana, @again-please, and @anacdoce if y'all would like to play!
