Mirelótë has never seen a giant mirror-faced snake before in her life, but since it eats her and thereby transports her to a bewildering novel location in so doing it's not a priority to figure out why this feels like just the sort of thing that would happen to her.
The bewilderingly novel location is an enormous hexagonal floor thirteen kilometers on a side. Past the edge of the hexagon there is forest and distant mountains. In the center of the hexagon is a small building. She's conveniently about half a kilometer from the building.
The large door of the building (about half again as tall as her and square) nevertheless opens easily. Inside there's a small pillar with a blue ring a bit below the upper edge. The room is otherwise empty and patterned in a hexagonal tessellation with colors varying from infrared to ultraviolet.
There's a sound a bit like an insect's buzzing but less regular from the pillar.
An image of the room in miniature appears in the air with her in it. A line is imposed from her miniature's eyes to the blue ring.
There's a feeling not quite like osanwë but similar. Confusion. You arrived. You are similar to human. There is a deluge of images of creatures which look reminiscent of elves but shorter with a wider variety in hair styles than an Elf would consider comfortable or proper there is also hair on some of their faces.
I don't know about humans, but they're not my species, they seem to have some differences according to your summary. I arrived via some kind of snake creature which ate me and this somehow resulted in my being here; this doesn't make a lot of sense to me, since it's not a normal occurrence.
I am disappointment. Humans and your arrival are mysteries I wish to be understanding.
Mother will damage their star and irradiate their world. They will not survive if not saved.
They have one world. Perhaps some could survive irradiation for a time. Some are burrowed deep. Mother will destroy them because All Mother demands or so say the books.
All Mother's gift of mind speech is not to be possessed by lesser beings. Humans will soon have mind speech. Mother will destroy before then.
I do not understand the gift but the seeds of it are already within them. Mother has seen them.
