On four pages you will be introduced to the Darklings as a playable race. They might be a bit special because they are fey and not of the good kind and therefore may not fit every campaign.

You'll get a short introduction what Darklings are and of course everything you need to make your Darkling character. The basis presented in the PDF is based on the Darkling Elder but you also find the rules for a normal Darkling.

Since the abilities are based on/taken from the entries of the Monster Manual with a few additions to make it a full playable race there are not balance issues which one or the other might fear.

So if you want to add some fey influence to your campaign with a Darkling npc or are sick of playing Drow character 259 and want something alike but different, you should give this a try.
