So a few days ago came to a realization, went a little bit mad, dove down a numerology hole and now I have a theory - the importance of numbers in TES all comes back to the Fibonacci Sequence*.
Specifically we have the first bit of the sequence. ‘0, 1, 1, 2, 3, 5, 8, 13’. We’ve got the void of nothing, Sithis, the Zero Sum. The two ones that make two; Anu, Padomay, and so on but also one by itself can be taken out of the sequence for all of its fancy relevance. 3 for the guardians, the tribunal, the liberators of cyrodiil, etc etc etc…
For a while 13 stumped me. Couldn’t think of any numerological significance to it in TES before I remembered the use of 13 as the division of the stars and their signs. 16, and its absence in the sequence at all, also threw me for a bit but works so long as you consider 16 as being not important in and of itself but only important in its relation to 8.
Anyways, this probably all reads like gibberish but it had my brain going
*For those not in the know, just skip this bit, but for those not an explanation; the Fibonacci Sequence is a fancy mathmatical sequence of numbers where the previous two numbers are added together to reach the next number. So, for instance, if you have '1, 1, X’ then x would be 2. Then the next number would be 3. And so on.
