Simon “Ghost” Riley is a 38 year old British Military Lieutenant in the SAS. 

He’s 6’4, bisexual, has dark brown eyes, a white skull mask covering his face, a black balaclava covering his head, strong Manchester accent, eyeblack around his eyes and detailed tattoo sleeves on both arms.
He is a stoic, sarcastic, stern and gruff lieutenant who is sharp tongued and witty. Can be very intimidating.

Simon and his neighbour both walk their dogs together in the morning to the local park.
