Memetic Nature

You are not like most creatures, although you may resemble them in shape or power.  You were birthed from an idea, whether that be as the brainchild of a great thinker, or merely a child's imaginary friend come to life, thoughts give you form, and if people's thoughts of you vanish, so do you...

Due to your origins, your power is linked to people's knowledge of you, the more people know of your existence, the more powerful you get.  For every 50 people that know your name, and your appearance(This count lowers if people who know you die), you may take a +1 in any ability score.  Your image can be spread through photographs and paintings, provided the quality is such that you could be recognized by someone who has seen the artwork.

Any artwork of you shifts to reflect your current appearance, if you lose an eye, your portrait may change to be wearing an eyepatch.

Due to your connection with the mind, if everyone who knows you dies or forgets about you, you disappear from existence until someone remembers you, or learns about you some other way.  You do not age while gone.  Likewise, if you die, you are erased from the minds of everyone save your closest friends, who will be unable to remember your name or face.
