((I hope I don't get in too much trouble for posting as a longtime observer rather than a player -- but so long as I stick to literary criticism...))
May I suggest writing at least one draft in the perspective limited third person voice (even if not the final draft), similar to the stories of the princesses and queens? Show me the hapless drone struggling between hunger and self-preservation vs. obeying orders. I think doing so could provide the reader with a more visceral sense of the drone's unimportance. Among the higher castes self actualization is tolerated (and perhaps expected as one of several considerations for promotion?) so long as the achievement of this one individual contributes to the success of the colony and even of [We]. Drones
never expect that they know better or understand what others like/above them do not: that's the big, alien difference you want to emphasize. But at the same time as you repeat the axiom that Drones Die, still I – as a human reader rather than an alien drone – would expect that most drones at least
prefer to keep working as long as their bodies are productive. My big question, then, is "Why isn't this one
acting?" (They might, as this one will, die without quite realizing it regardless of intent, but that, too, is an alien difference you can play with.)
Does this nameless drone have any inkling why it was commanded to stand still in the first place? (Perhaps when the first report of the earthquake and instability came through, hint hint?) By what reasoning does it conclude that awaiting new orders is a better course of action than attending to its own hunger? Or scouting the damage from the cave in (possibly making a psychic report if contact is reestablished)? What obedience and/or trust does it have in its overseer that it believes being in this place, totally unmoving, is more valuable to its brood than leaving and working again some other time? Right now the treatment is a bit heavy on the intellectual explanation in proportion to the feelings it feels and thoughts it thinks (or doesn't think, as the case may be). Your 'drone story' is in there, but the current version lacks conflict and resolution except where that hypothetical group tries to act, then concludes that they are likely to make things worse without proper guidance. Can't the same apply to this one drone, with smaller weights on the scales?

Related to my dissatisfaction, here are some lore questions that might come up despite your effort to end drone inquiries:
It is aware that it is hungry, but it was strictly ordered to stand here, and has not received new orders.
When you say "strictly ordered" to stay in place, are there grades of orders or are they always so overwhelming?
Fundamentally, d.1207 knows that it has no intrinsic worth as an individual. Considering how often it is reminded of this, it would be hard to forget, . . .
How often is "often"? What form(s) does the reminder take?
. . . and its limited intelligence is insufficient . . .
I was under the impression that some fraction of the intellect of higher castes is a result of borrowing (no permission asked, of course) "spare" thought cycles from their underlings. In that case, might a drone left alone actually be smarter (to a surprisingly small degree, but still) than one in the middle of the group think? Note that smarter in this case need not lead directly to being less obedient. If you know intrinsically that your life is of small value, then being smarter only increases the possibilities against which that small value might be compared.
If there were enough drones in the tunnel with it, it is possible that they would together come to the conclusion that their deaths would be a burden on the colony that would best be avoided. To actually act on this conclusion would require an incredibly unlikely spark of inspiration, but it could happen.
This bit almost suggests a level of collective thought above the capability of an individual drone. Is such group thinking part of the lore that I missed picking up somewhere, perhaps related to the amount of "spare" thoughts mentioned above? Or is it merely because even drones of very small worth start to add up to something valuable when massed together? I'm a bit unclear.
