Oberon had four basterd daughters with his long-time lover and paramour, Ellaria: Elia,...
...Obella,...
...Dorea,...
...and Loreza.
Just like his wives he had a personal body guard, chosen from the best of the Fae warriors,....
...as well as a light armored scout unit.
Apart from those smaller units there was also a brigade of flying Fae to deal with small threats from inside like small and medium predators....
...and a legendary force of cullahan, Fae without wings, that can be taller than humans.
