This world was formerly known as SHMUPS Domain. It was originally intended to be an optional world focused heavily on SHMUP (shoot 'em up) games (such as R-Type and Gradius), but was changed into a fantasy setting world due to the following reasons:
- Programming difficulties of the now ill-fated SHMUPS system, which was scrapped.
- The impracticality of sticking a genre-shifting game mechanic in MKF, which, at this time of writing, already has so many other game mechanics crammed into it.
- The similarity in theme between SHMUPS Domain and World 9 (Edge of Beyond). Both had an outer space/sci-fi theme; there was no point and even unfair to the other unrepresented and underrepresented games for there to be two worlds with a similar theme.
JudgeSpear admitted that SHMUPS Domain was a vanity addition, since he is a big fan of the SHMUPS genre. With the culling of the SHMUPS system, the SHMUPS Domain world became useless and expendable. The existing SHMUPS-themed level, Bydo Station, was moved to World 9, along with SHMUPS Domain's plot.
