Titans are a type of monster. They look somewhat human-like, though their proportions are often not quite right. Most titans stand anywhere between three and fifteen meters, though exceptions have been recorded. All we know is that they suddenly appeared a bit over a century ago, and decimated the human population. The only survivors were the people who were able to flee behind the walls. Or at least, that is how our history books tell it.

They lack the ability to speak or communicate in any meaningful way. They seem to possess some ability to learn, though, like most things regarding the Titans, we have no idea to what degree. The only thing we know for certain is that, despite lacking any sort of digestive organs, they are singularly driven to devour humans.

As for talking about the outside world or making any attempt to visit -- this is considered treason and is punishable by death.
