004 is a broken unstable experiment. Originally the sparks reaction to too many bonds was to mutate and split the experiment into four versions of itself. Each of these facets, 005, 006, 007, and 008, have shown signs of two or more active sparks and some decent control over them.
Unfortunately it is believed their split was not a cloning as originally hypothesised, but rather a clean cut of an individual into four. This left the experiments incomplete and inefficient, on the edge of collapse. However, attempts to force reverse the process have indicated potential fatality along with immense destruction.
005, 006, 007, and 008 are currently being stored in an isolated set of units from the other knights and experiments. The four have shown an increasingly different array of attitudes and reactions towards testing. It is hoped that further isolation may allow them to mature into more stable states.
There was an issue with a bonding and the four had to be relocated, upon reintroduction to each other the spark pulled them back into one. It does not seem any more stable in this state but refuses to separate at this time.
004 is believed to currently trying to host 8/3s of a person with over 10 sparks at once. This has left it volatile and unstable. While only two sparks have been recorded as active it is vital we get this experiment under control immediately.
004 split again today, and the facets have been determined to still not be fully whole and do not seem to be improving further. Before this 004 was stabilising and beginning to show comfort with its sparks enough to consider becoming a knight.
It has been seen that the sparks active in 004 are not in 005, 006, 007, or 008, instead the other dormant sparks have split themselves amongst them. This could be a useful trick in a fight.
004-008 have shown negative response to extended periods of separation or fusion. It is believed that it has evolved too far as faces to neatly return to a single, but has not evolved enough to remain split. However, it has recently been introduced to the other knights and is fitting in well. It will bring a good level of balance to the team.
