Darkling literally means 'IN THE DARK'.

It's also a word for things that live and occur in the dark and it's obscurity, surrounded by a vaguely threatening and menacing atmosphere. 

So basically, at darkling, we sell collectibles and merchandise from the dark side. It's about villains, foes, rebels, anti-heroes and all those critters and creatures who you would not like to meet at night - or would you?!
