Nice grid, with three fairly easy groups and one which I found really tricky; hard to spot hidden words when they are so short. Speaking of which, it would have been nice to have a more thorough explanation of the "Nepit" group, going over each item like in the explanation of the "Horus" group. Of course it's not too hard to piece together oneself, but still.

I guess the key is spotting why precisely it says "Deerhound". I didn't so I got two groups and couldn't sort out the right members of the third. Good grid though.
