Nightmare
Yuki is lord of heaven and earth
From typemoon wikia: http://typemoon.wikia.com/wiki/Lord_El-Melloi_II_Case_Files
The world of Lord El-Melloi II Case Files is set as the same parallel world of Fate/stay night and relatively closely to Fate/Zero, as Waver Velvet had participated in the Fourth Holy Grail War.
Waiting for official announcement....
