"If someone will sing me a song to calm down an animal which would work on hostile ones if it were sung fast, I can make sped-up copies of it that sing themselves and attach these copies to objects. Would that be useful to you?"
"Do you have any other songs which would be useful like that?"
"Would you be willing to let me copy some of them anyway?"
And she walks out of the forest back towards the Men.
"The people in there really don't like visitors," she comments.
"They're actually a species called Quendi or Elves. There's other tribes of them who are friendlier than those ones, but all the ones I've met are far away. These Quendi are really not interested in making friends and you should probably leave them alone. They implied you have trouble scaring off wild animals?"
"...Demons besides the Quendi in the trees?" she clarifies. "Are there other kinds who don't live in the forest?"
...okay, she cannot quite explain all of that as tree-dwelling Elves. What do the shapeshifting demons turn into once they aren't humans anymore? What do the water-creepers look like?
Loki did not discover she's an adopted werewolf, but she did hear that those were a thing.
Do the demons come from any direction, or only some directions?
Loki thanks them and wanders somewhere out of sight and then flies invisibly across the lake. She wishes to be cautious here; the illusion notes are underground and she is properly invisible, not just sky-shrouded. She does not play the speed song.
Oh, good for them! They came up with stone buildings already, look at them go! Anything else around here more demonic-looking than that?
She swoops around, sees nothing but clever stone-building Men, and finds a place to land and change hidden and pops out.
