Go right ahead. Happy that my character has inspired you! Amd indeed the Ballmer peak was an inspiration for this character.
As for more details, my character is Mazarazan, a dwarf artificer that was gifted with an unatural proeficiency with magical artifacts and an even more unnatural ability to understand the very fabric of reality. The later ability, however, came with caveat that due to the sheer amount of arcane knowledge about reality he possesses, the knowledge itself started to become conscious inside of his own mind. And turns out, pure magical knowledge about the fabric of reality given consciousness does not form a sound mind. That second consciousness latched onto his own and essentially fused together, while still remaining relatively independent, and without any inhibitions, they are in a constant battle of wills, trying to hold control over the body.
The parts of his mind couldn't be further opposites. Mazarazan is methodical, cautious and deliberate in every decision he makes, always trying to see the ramifications of his choices and the consequences they would entail. His counterpart is volatile, impulsive and maniacal. It always tries to acquire more knowledge to expand itself, and takes actions mostly based on impulse and emotions.
Mazarazan is guided by scientific curiosity and strong morals, focused on making a science around the fabric of reality, so that the whole world may evolve and progress into horizons unknown and overall be a better place to live in. His counterpart, however, doesn't share those pesky morals always getting in the way. It is guided exclusively by (sometimes not so) scientific curiosity and it's thirst for knowledge. However, it is always up for some practical experiments, which usually end up in a new war crime being invented.
A fluid gets too hot and compressed that it forgets it's supposed to be either a liquid or a gas, so it decides to be both.
