Rod Reiss

Lod Reiss (ロッド・レイス) is a a member of the true royal family within the walls operating from the inner lands of Wall Sina. He is the father of Historia Reiss.

History
Lod Reiss conceived Historia with an attractive maid and his lover and daughter were exiled to a land that he leased to Historia's maternal grandparents. One day Lod came to get to daughter and inform her that she would be living with him from now on, only for Kenny Ackerman and the 1st Brigade of the Central Military Police to swarm around his daughter and Historia. Captain Ackerman questioned if Lod was familiar with these two woman which he than denied. Lod watched as his once-maid was slit at the throat denying being Historia's mother. When the former serial killer moved in to kill Historia, Lod suddenly proposed an alternative of having her enroll into the Survey Corps and hopefully die in battle. Seeing this as a fitting alternative the Central Military Police agreed to this demand. Presumably Lod left with the Military Police.

Abilities
He is also stated to be the most powerful and influential man inside the walls as he is a member of the royal family and his power reigns supreme over the false monarchy's supposed authority, and has command over many of the governmental layers of power including military and religious methods of control. However his power does not seem to be absolute as Captain Ackerman apparently takes orders from someone of superior authority, and many deny his daughter as a suitable heir to the Reiss Family. In the end his influence was still enough to propose a suitable alternative.

Relationships
Historia Reiss: Lod is Historia's father, though she is an illegitimate child who is not accepted as a suitable heir to the Reiss Family and thus Captain Ackerman was charged with her death and the death of Historia's mother. Lod came to get her to live with him, but the Military Police interfered and rather than take back his daughter, Lod was forced to propose an alternative where his daughter's chances of survival would be extremely low rather than see his daughter's death before his eyes.
