Scottish mythology, actually. The word 'trow' or 'drow' refers to a type of troll, goblin or malevolent elf in the folklore of the Shetland Isles, which are part of the north-east of Scotland. They do also take a degree of influence from the ideas of 'svartalfar' in Norse mythology.

As to the topic, beholders all the way.
