[@HueMan] His domain could be similar to how Sombra's works then. Her domains work by association. Secrets bring in Conspiracy, with Conspiracy comes violence and crime. She seems like an evil god, even with her innate delight of sadism (as much as she tries to hide it), but she's not. She's needed for proper civilization. He could be the God of Abstraction. Abstraction is what makes sentient creatures more unique than feral beasts. They are able to conceptualize tools with abstract thought, and under stand emotions like love. Abstraction also helps us understand math, which is primarily symbols and figures, as well as science as it needs to be broken down before an effective law comes. But like Alice and Wonderland mentioned, everyone is a little mad. Madness will be part of his domain, though it'll probably be a lesser field similar to Sombra's Crime and Violence. But like her still, he is needed for civilization to work. One is a motive to drive towards it, the other is the ability to draft a contract to create such.
