Question

What about Dr Matin King?

Answer

It should be noted that in order to place these varied events into chronological order, and to get the best sense of the Leagues' activities, there is some speculation as to probable times and orders of events, as well as mention of several events which, while happening to characters contained in LoEG, do not actually occur in LoEG, but in the original works the characters were taken from. Since LoEG is a crossover fiction, there are several events which the writer of LoEG will assume the reader already knows about the character, and these events can be considered canon. At some points, however, the fictional canon of LoEG comes into conflict with the worlds of the various fictional works used as components of the LoEG fiction. These places are clearly marked, but as a general rule, unless specifically noted, the events of the sampled fictional canon all are assumed to have happened as depicted in the original work, with the addition of being in a world in which the events of all the other fictional bodies have taken place as well.
