My story revolves around a woman with a special power to communicate with ancient alien AIs that live inside "computers" in underground caverns built by the same alien species (the species itself is thought to be long dead). The underground caverns themselves are essentially subterranean highways (similar to this: http://dragonage.wikia.com/wiki/Deep_Roads), and exist on several different worlds, including the 12 that humanity occupies. The reason for this vast underground network is hotly debated, but what is notable about it is that there appears to be randomly spaced "statues" of the aliens who built the highways. These "statues" are really just large daises that project holographic representations of the AIs themselves. They appear as statues because they look exactly like regular old members of the alien species and essentially stand stone-still, not interacting in any way that would make the humans who encounter them think they are anything but some intricate and beautiful type of idol or figurine. Flash forward to when this particular woman is born, it is eventually discovered by the government that possess the ability to speak with these AIs, and more importantly, can cause the AIs to open wormholes that lead directly from the underground highway of one world into the underground highway of another world. This becomes important, because she is essentially enslaved by the government to help them use this method of transport as well as her ability to interface with the AIs to discover the location (and then later travel to and obtain) a theorized ancient weapon that the aliens built. That was long-winded, so I hope it wasn't too confusing... Getting to my plot-holes, I am trying to figure out: 1. A reason why this woman would have obtained this special ability. 2. A reason why these complex underground highways were built and interconnected. Reasons I have come up with thus far include: 1. - She has an incredibly rare genetic condition that required specialized treatment with a computer-brain interface at a young age which has essentially taken over her immune system, and for some techno-science-magic reason her cellular profile becomes similar enough in some way that the AIs erroneously recognize her as one of the dead aliens. - She was given the ability for some reason by one of the AIs near where she grew up. 2. - The highways were built by a species which lived underground. - Built by a species which was harmed by sunlight (maybe they evolved on a neutron star or something) - Built to avoid detection by something. Anyway, if you have any good ideas you can throw at me, I'd love to hear them.
