Lóndrangar. With her kids. Climbing all over her, really.

And isn’t that her mate on the right, staring off into space? Why not! Even an ogress has a family life!

She is not absent from it. Every ledge on the mountain has a name. Each is a separate sheep pasture. Talk about trusting ancient forces with one’s sheep (the “hidden people” just seems wrong, given how visible she is), or what.
