Today, almost six years after Part 1 was published on the Lifestream, the final numbered installment of the Unused Text Series at last graces the web.
One can compare Part 12 with the defeating of the final boss: The ending credits may have rolled, but there are still many sidequests or even post-endgame content to be explored. The sidequests in regards to the Unused Text Series would be dissections of the Debug Rooms and some complementary appendices.
I can't promise that these "sidequest" articles will ever see the light of day. I have now reached an epic milestone and I am simply going to enjoy that fact, without the burden of any feelings of responsibility for the future of this series.
My gratitude towards hitoshura for doing the translations for Parts 11 & 12. Many thanks to everyone who has supported this series and helped it get this far.
