After Halo: Escalation #10, we know (or think we know) the final fate of the Ur-Didact (the Didact you fight in Halo 4). Ever since finishing Halo: Silentium, though, I’ve been curious about his “twin”, Bornstellar Makes Eternal Lasting / Iso-Didact (hereby called Iso-D). The last I recall of Iso-D was him firing the Halo Array from the Lesser Ark to stop the Flood’s corrosion of the galaxy. We are left to assume his utter demise at the hands of the Array; however, I’m not so sure this is the last we’ll see of Iso-D.
Take into account that everything that is done with Halo cannon is methodical and purposeful. If 343i decides to not specifically showcase the Iso-D’s death, then I believe there is reason behind this.
Do you guys think the Iso-D is still alive (whether in a Cryptum, or otherwise), and will make a physical appearance in the upcoming future of the Halo canon? Do you think the Iso-D is as dead as dead can be? Or do you think the Iso-D will live on in other, more clever ways?
I’m personally of the opinion of the last option. Consider what Iso-D asked Chakas/343 Guilty Spark while on the Greater Ark in Silentium. He asks Chakas “Tell me Chakas, if it was your choice, after all we have seen and survived… would you fire the rings?”. The next time we see a mention of this is in Halo: Combat Evolved, where 343GS says to Master Chief “Last time, you asked me, if it were my choice, would I do it?..”. It seems clear from these statements that 343GS views Master Chief and Iso-D as the same being. Whether or not this is true remains to be seen, but I have a theory of why this comparison is made.
I theorize that Master Chief has had a gaea placed within him, and that his gaea contains none other than the Iso-D. We already know that the Librarian specifically planned for Master Chief’s presence. This could hint that she further planned to aid Master Chief by giving him a gaea. While we have yet to see a gaea of a Forerunner placed within anyone, that isn’t to say it isn’t possible to do. Even if the process was rare or difficult to do, I’d imagine pairing the likes of the Iso-D with the future “salvation” of humankind and/or the Mantle would justify such an act. John-117 having this gaea could explain several things. We have known since close to the beginning of Halo that one of John’s primary unique characteristics is his luck. He was just “lucky” enough to know what to do to activate the light bridge in the belly of Alpha Halo, etc. What if this came naturally to him not because of his luck, as much as because of the Iso-D’s subconscious guidance?
You might be asking, though, why Iso-D would then allow John to almost activate Alpha Halo and wipe out the galaxy. I suspect that was more because just as John took 343GS at face value, Iso-D must have assumed his former friend still had human judgment left within him, though we find that this is far from the case. Iso-D would have felt more betrayed by 343GS/Chakas than John did.
Also consider the similarities between Iso-D and John-117. Both had their fates altered by another force to become a much greater leader than they could have been otherwise. Both were physically altered to become much stronger and more powerful to do the added tasks given them. Both consider the greater need of all life’s existence moreso than their own existence though the service of life (and/or death).
Ultimately, we don’t yet know what Iso-D’s fate was/is. I’m just wanting to lay all this out and hear from you guys. Do you think we’ll see from or hear about the Iso-D again? If so, how?
