You had passed out, your sleigh beggy body strained by the constant output of magic.

Elias,after panicking slightly, laid you out under a tree in the peaceful garden close to the forest surrounding the cottage. After all, nature, and being surrounded by the neighbours/fairy folk would help heal a sleigh beggy like you.

Except, of course he couldn't banish the churning feeling he didn't understand seeing you unconcious, so he simmered in the shadow of the tree.
