[quote]Are young prophets still sensual and strong, or are they too inbred/genetically bottlenecked?[/quote]Yes, they are still sensual and strong. The only things that changed is their cultural relevance on who's important and respected. Now it's the elderly who are revered and respected. [quote]Also, do the lekgolo build things? Do they have science?[/quote]Yes. When the Covenant found them they were capable of space travel. [quote]Why can't the drones fix things in kilo-5 (I'm guessing silly traviss is at blame here)[/quote]They can, however, they are only capable of short term fixes compared to what the Huragok can do. [quote]Did ancient prophets have insanely long life-spans? Considering the deal the didact had with the elder.[/quote]It would appear that way, yes. It's unknown if that's their natural lifespan though.
