Use the LAI or SAI template, but delete Taboo Trait (mental instability). Add Amnesia: Partial, shallow memories (-70%), (-3). Add Delusion: I have full memory (-5). The shadow's basic outline of memories is accurate, but many details are manufactured or simply not there: It's like the difference between a good biography and a person's actual experience. The shadow is programmed not to notice this. When creating a shadow, keep mental advantages. Divide points put in physical skills by four, and points put in mental skills by 2. Buy the highest skill level that those points can afford, and drop points in excess of that.
