Using Sali as a background information source is reaching I think. While I am sure she learned that is school she left a whole bunch out. She probably didn't listen while reading one of her adventure books.sonicthunder wrote:This has been your daily dose of exposition. Thank you for listening.

That line about theri tech being powered by the genes in the bodies is interesting though. It implies that the genetic coding is needed to make it work, or that they incorporated their own DNA in building the technology.
If they included their DNA then they were breeding machines and devices to do things for them. Very little evidence would remain as most living devices have limited life spans when not properly cared for and fed. The only real evidence of that is the Golem Girls. They were the result of biological experimentation after all.
But we have seen mechanical devices from these civilizations that have lasted, like the calendar machine. The crystal dolls. The gates. The genetic keys would limit the users quiet nicely. It also implies that Maya can still use the network.
