Great post obscurus! I rather enjoy all the different angles everyone is taking.

@Termite: I hope my post was okay, I know chlorophyll is a big step but modern science suggests that the first algaes were formed when a photosynthetic cell collided with cells with developed mitochondria and created plant cells which created energy from the sucrose and utilized it via the mitochondria. If I remember properly. 

I've already given my Entity a problem, can any of you find it? The road to perfection is one with many trials and errors :P
