Timing for this Omake is a year or so after Ridcully returns home, after the current war. Hope none of the appearing characters die!
Proposal to change the language of instruction in the Adaptus Astra Telepathica
Fredrick looked down at the scrawled note. "Munstrum, you're going to have to explain this to the high council." The seer, sitting opposite, crossed his legs and scowled. "Using a Xeno language to train psykers will not go down well with, well, the inquisition, the mechanicus, and the conservatives. Have you at least spoken to Markus about it?"
"I have. The high council will get over it without sanctions on the telepathica or Averneus. They will be unhappy that I took the issue out of their hands, but what do I care if the oh so wise and mighty Bertil Mikkaelson gets his knickers in a twist. They're perpetually in a twist anyway!" The governor stood shocked in disbelief for a moment before remembering who he was talking to. He'd missed the brusqueness of the Archchancellor, even if he wouldn't like to admit it. "Munstrum, you know as well as I do that keeping the other worlds on side is important. Getting personally involved with galactic powers doesn't change the fact we rely on the trust worlds, and despite you now considering the high council the Kiddie Table they are at the very least entitled to an explanation as to why you intend to start teaching in bloody eldar!"
......
High councillors.
Upon first coming into contact with the Eldar Seer known as Eldrad Uthuan, I decided that the time had come for me to learn the language of the Aeldari. With the aid of a few lovely members of the Ordos Diologus I was able to pick up the language to a certain extent and I began to see some potential in it. It's extremely difficult to explain properly to non pskyers, but the language seemed closer to the reality of the warp. It described concepts we absolutely haven't got in any known dialect of gothic. I started using Eldar loan words in explanations, and soon they became widespread across the university. We use Aeldari terms already you see, as a decent chunk of our vocabulary became unusable following the rise of the abomination, and as soon as I found good replacement words I slotted them in. Seamus remembers me telling him this, don't you.
At this point however, my understanding of the language was very poor, comparatively to even an eldar child. I could make myself understood in it, and translate the first couple of levels of meaning, but the higher inferences, which it turns out are very useful for explaining psychic concepts, were beyond me. However, given my recent, extremely successful, but rather unpleasant stay in the black library I have become intimately familiar with the Eldar tongue, although calling a language that is 37% psychic a tongue is stretching it.
This experience has lead me to the conclusion that starting immediately all Adaptus Astra telepathica outposts should begin rolling out the Eldar language to every psyker, with the goal being to begin teaching in it within 25 years. Studying the language, I believe, and a number of the Eldar classics written in it, will in itself have a positive effect on the students, the experiences and tales of a psyker race having developed over time to be optimum for training psykers. This compares to our own language, and tales, which daemonize the witch. Reading the Eldar classics would have helped me greatly as a young man, would have helped me understand what I was better, and would have helped me understand the dangers of the warp better too. The daemons of the warp have a slippery grip when you speak to them in Aeldari.
Not only does the language itself have a positive psychological effect. It also has great potential for research. Multiple times, it has a hundred words for what gothic has one, and a number of our research teams are already learning it as a side project. They are already seeing some quite significant improvements in their progress, especially when dealing with runes.
Teaching in Eldar, also, I think would allow for faster understanding from students, so we could teach them more before their trials. Experiments have shown that if teaching the language commences at an early age, young major psykers pick it up incredibly quickly. Admittedly, the net benefit to minor psykers is much lower, but for major psykers learning in Eldar leads to a not insignificant increase in learning rate and therefore, pass rate.
In conclusion, the widespread adoption of the Craftworld Aeldari language, preferably the academic Uthwe dialect, would see very significant net benefits, with higher quality and faster research, better tuition, more resistance to the terrors of the warp and correspondingly higher pass rates. These effects are due not only to a greater vocabulary, also the structure of the language makes more sense in the warp. If it were possible I'd have every child learn Aeldari from a young age, but I understand that this is an undertaking beyond reasonable possibility. Teaching a million children Eldar just for the benefit of the one major psyker is wasteful, even by my standards.
Yours Sincerely Xeno Archchancellor Munstrum Ridcully.
