I have not read the comic series so if Terminus refers to something directly with the comic series, forgive me for my ignorance in the Walking Dead universe.
Regarding Terminus, the yet unseen safe haven for survivors, seems too good to be true…especially since there are signs up posting where to go. In Roman religion, Terminus was the God who protected boundary markers; the name was the Latin word for such a marker. Sacrifices were performed to sanctify each boundary stone. An annual festival, Terminalia, was celebrated each year on February 23rd to renew this foundation ritual. It was considered sacrilege to move boundary stones. He protected not only private property but also state boundaries. Offerings to Terminus were crops, honeycombs, wine & garlands.
I wonder if that background of the word plays a part in this series. What are your thoughts on Terminus?
