The Lincoln is not any one person, but a comittee of elected Nobles. One requirement of the Noble is that they be a living Saint. The Majority of them attain this degree through the completion of the role of VSD, and through the unanamous consent of the citizens of Underground America.

When he appears to the citizenship, he appears in front of the "Black House" and the burning flag, as per a tradition which dates all the way back to a time when those flags existed on old Earth.

When a Noble speaks through the Lincoln, no one knows which Noble it is that is speaking. Occasionally, when something important needs to be addressed, or when a large public facility is completed within the grid, the Lincoln will address the entirely of the citizenship.

As per ancient tradition, the Lincoln will begin by stating "My People" and the people will salute him with a raised fist with the middle finger raised and oriented toward wherever it is that the aparition is appearing. In unisine they entone the motto: "Rebellion to Tyrants is Obedience to God"
