Nikola Tesla (or "Nikky") is a Callahan's patron based on the real-world historical figure of the same name. In the Callahan's universe he was granted immortality by Lady Sally under the condition that he would fake his own death and disappear from history. He was also taught to transit and translate and spends much of his time in other fictons.
