So Artemis has really healthy ways of dealing with anger. In the next few days, no one will be able to get in touch with her, but Diana's Hunt will launch some very aggressive operations against the companies and people hurting her forests and the wilderness. Aggressive enough that people will die. Also there might be a mysterious plague infectious disease or two striking in the Amazon rain forest, weirdly contained to deforestation sites and the people working there. Will you look at that, the natives will be immune. Also expect random poachers getting shot dead (arrows, obviously, not bullets) in Africa. Etc, you get the gist.
For those of you whose gods would wanna get in touch with Artemis, it'll be a little while before she gets back to anyone. No one at her camp will know where she is or how to get in touch, including Orion.
