See, Decimal 25 is equal to Octal 31. Furthermore: hexidecimal 19 = decimal 25 = octal 31 = quadral 121 = binary 11001
It's an old math joke that was obscure enough for me to try and work in some flavor for the universe. The font is screwy, but you can see that the Technomancer's name is Gibson, and the Summoner's name is Abraxus. I'm moving away from the 8-bit Theatre thing where the characters are named after their class, and more towards a society where people of different character classes tend to call each other my their titles.
If you look really really close at the thing that the Technomancer is holding, you can see that it's a PDA/cellphone thing with a crystal and feathers attached to the antenna, and sigils on the keypad. A Technomancer can use arcane knowledge to imbue technical objects with magical properties, thereby extending the already impressive capabilites of modern electronics. These devices are known as Magitech devices.
