Cool cool, have some free time now, I've decided on simic hybrid, spore druid, old ones warlock. Was really going for the "im an alien" feel.
Some background
The character focuses on genetic alteration via magical, or fungal, means. It was already genetically modified at birth as all simic hybrids are. Later in life it took to the druid path and the character found it to was interested in making a superior species. While out harvesting a specimen it found itself exposed to mutated fungal spores. It had stumbled in on another druids experiment, who happened to be a member of the circle of spores. My character promptly joined, very interested in the mutagenic properties of these spores. Once it found it was exposed to the spores, it did tests and conducted more research. After a while it was doing some field work and researching in a very secluded area, it stumbled upon an ancient tome of forgotten lore buried in a very old grave. It read it and had its mind assaulted by other worldly entities that promised the knowledge it sought in exchange for services rendered. It's been searching for more such knowledge since.
