I think you may also have slightly missed the point, despite being an entirely separate area, magic still works in many ways like the science/technology that we are used to. In the sense that scholars/mages work on the knowledge gathered by predecessors to enhance and expand their knowledge. Therefore it can be said that over time magical knowledge, and so the use of magic in architecture and other aspects of civilisations would be developed, refined and increased. For example, the falmer could have hyperthetically created much more advanced portal systems were they still around as over the thousands of years they would have been able to find flaws in the previously used spells or found a more efficient magical method.
From this I am deriving the statement that the utilisation of magic by both the falmer and the dwemer seems to be much more complex/advanced than that of current day races despite the thousands of years that the current races have had to improve their knowledge of magic, not due to a rise in intelligence but rather due to generation upon generation of different views and stances towards the magical discoveries of their predecessors allowing for different methods of utilising the knowledge for more efficient/effective effects. This doesn't even take into account the discoveries of certain locations/natural phenomenons that would have expanded these cultures' understanding of certain magical principles.
I am therefore stating that given the advantage of time that these races have had they seem to still be far behind the capabilities of these other, closely-related, races. This leads to the conclusion of one of three things
- The dwemer and falmer had a naturally higher intellectual range/a better understanding of magical principles leading to a much faster and effective use of their magical knowledge to create the things they have
- These races had access to certain things, or their culture allowed for the better research into certain things, leading to a faster arrival of certain discoveries that allowed for more advanced technology
- The other mer races do in fact have similiarly advanced technology however other provinces have not been made aware of such technology
Ah, but the arena is a dangerous place and entire civilisations are wiped out at the drop of a hat.
Id have loved to meet a Kothringi.
In any case, the classic trope of ancient knowledge barely remembered is effectively averted with people like Vivec, Talos and Divayth Fyr.
Let us also not forget that during the third era the Empire Cyrodiil maintained an artificial pocket dimension to house its battlemages, the Battlespire.
Technology (or magic) far beyond what we are capable of.
Not everything is a reconstruction of powerful artifacts past, and because I find this notion of a mythical dawntime where everything was better and modern people are just rediscovering stuff to be utterly boring, I reject it.
Youre right about us not having seen what the other elves (Altmer) are capable of. They move islands seemingly at will, control weather, pierce the heavens and program the Mundus like it was wysiwg.
