If anyone who created this race, here?

And is it okay if I use it?

That page lists an author: "by Desmon Arnold"

You can, if you so choose, support him on patreon, via a link on that page. 

I doubt he would object if you use it, he appears to have made it pretty public.  But I am SURE he would appreciate a Patreon contribution.

Note, I consider that race to be overpowered.   Bindsight 60 ft for all, and the subraces have even more power.

Well at my adjustments. It shouldn't be that overpowered, I'm using savage world rules, and mostly theater of the mind combats. But thanks for the details!
