Jylia Shale was a strategist and a general with the Imperial army in the novels Aftermath and Aftermath: Life Debt. Shale did not think the Empire could outlast the New Republic and that the Empire was in denial about their situation post the Battle of Endor.
After being captured by the New Republic Shale ended up cooperating with them. This eventually led to Imperial true-believer Gallius Rex ordering her assassination.
