As a start, I have built a device that artificially creates Heartless. By recreating the conditions that spawn the Heartless naturally, I should be able to produce them artificially. This device is the culmination of all my research thus far. The machine's test run successfully created a Heartless. This may be a step toward creating a heart from nothing.
The artificially and naturally created Heartless showed nearly identical traits. But the two types remain distinct for the purpose of the experiment. So, I will mark the ones that are created artificially.
