The ceiling was a nest of large cooling pipes that fed the great lake above ground. Alice’s mind screamed at her to move, run, get away, but she fought it and concentrated. Any MI system powerful enough to run this place needed power, cooling, and data.

Below the place where the pipes terminated was a small steel door with an armed guard. This was the first guarded room she had seen; that door led somewhere important.
