Perse knows she can not save everyone, not those that are tightly bound up by the Fates in the the threads of a Great Prophecy.

She could not change Luke's fate, or Thalia's poisoning, or Artemis's kidnapping. All were pre-written in prophecy.

However, saving demigods is her domain.

She has to try.

("It's a tragedy...but we sing it anyway" - Hermes, Hadestown)

And with those less lightly bounds, she succeeds. (With Perse, more demigods make it camp. Some still die. But others don't. The Demeter cabin is fuller. Silena has more siblings to look after. Nike's twins arrive at camp. This change, smaller than Perse wishes, has a ripple.)

I like modern epithets and all but we should not be taking an indigenous American word, that was already forced into a European-ized transcription, and make it sound Greek and then use it an epithet for a Greek God.

Like at most "Athena of the State of Massachusetts", if you're asking her to protect the people of that state... I guess. But trying to make "Massachusetts"— word derived from a Wôpanaâk language—sound Greek and make it seem like a historical Greek Epithet: Athena Masachouséti, when Massachusetts is the name of a Native American Tribe....... is just not something we should be doing. This goes for landmarks, mountains, forests, deserts, localities that use indigenous derived names.

I'm going to say I'm 100% against taking Appalachia—a word for a mountain range named after the Apalachee Native Americas, a name the Spanish used to refer to them, which may derive from the Hitchiti or Choctaw languages—making it Greek sounding "Apalákhia", and applying it to Artmeis as an epithet Artemis Apalákhia is wrong. Just say "Artemis in the Appalachian Mountains" if you are there and want to invoke her, alternatively just use "Artemis who is with me / who is here" and avoid it all together.
