The alchemist that forgot to die

It was not sudden, nor a progressive and noticeable thing.
just that one day, he realized he forgot it all. Breathing, food, the
need to sleep… He always seen that as an hindrance to his magical
studies, and years (decades ? centuries ?) of training his will to bend
reality must have shaped his body to what he have become.
No need to wonder about such a small thing as immortality. There is still many mysteries to learn ! Many secrets to reveal !
