Elizabeth Miller is a member of DPIR, or the Department of Phenomenological Investigation and Research. She is sent in with two other people named Josh Li and Kate Wilson (never shown) to investigate the appearance of the Astre Sucre factory. She is generally very professional and contemptuous. She nearly dies twice, once on updates 451-875, and once from 1170-present. As a device, Miss Miller is used to keep the story from sidetracking much further than it already has and speeding it towards its conclusion both when she questions Amie to get the party together and when she appears with a gun during the big Gregor fight scene.
