So, looking at the symbol and thinking about the portmanteau for "Omnitome" (omnipotent + tome), I did a quick look for "symbol of eternity".
I managed to find a lot of similarly-styled designs to symbolize eternity in the quick image look, and since the Omnitome is (presumably) supposed to be a book containing all knowledge, my educated guess is that the symbol is perhaps meant to relate to that--omnipotence, eternal knowledge, the book in which all things are found.
