The following was a conversation between Dr. Stephen Franklin and Citizen G'Kar after latter has been fitted with an artificial left eye.
Franklin: There is a rumor that after Narn [G'Kar's homeworld] was freed
your people wanted to put you in charge. Is this true?
Franklin: Why didn't you take it?
G'Kar: I've seen what power does and have seen what power costs. The one is never equal to the other.
