Elnor really is underdeveloped. His relationship with Picard, which is his emotional center, is much more “tell” than “show,” despite a lengthy flashback when he’s first introduced. I can’t say he’s one of the series’ standout characters, but I do think he may be conceptually the most interesting for me.
Elnor is an example of one of the things I yearn for most in science fiction, one of the key reasons SF&F are useful genres for me: an exploration of a truly different cultural perspective, a truly different stance toward life. ( light spoilers )
