"The horizon is painted purple and an alien landscape dominates the scenery as you take the first step outside. This planet has been taken by the amalgamate. A layer of the viscous oil like goo gives resistance under your feet on each step as you pull the gas mask over your face tighter. A film of dark haze covers the ground and makes way as you walk forwards, the ground seeming to constantly shift and move beneath. Above in the sky a thick layer of similar colored clouds fill the sky, the sun peeking from below them, a stagnant unmovable mist fills the air. Looking around the environment things seem faintly familiar but hopelessly unrecognizable as the amalgamate has built itself upon everything. Massive pillars reaching towards the sky to leech on the sun above the low hanging clouds and mist. More of the amalgamate seems to constantly ooze from the innumerable crevices and holes within the plants, the amalgamate still seemingly working on converting the organic matter underground. How long were you asleep? Some of the amalgamate forms remain in the landscape, moving around almost aimlessly, even though they could sense you, they take no notice, but you decide to stay out of their way anyway. Clearly they too know that there is nothing you could do to the amalgamate at this point. The presence of these wandering creatures seeming almost as pointless as yours. The only hope now is that some of the members of your species made it out into space and are heading to another planets. You sigh as humid fog gathers inside the mask as you sit down to wait for the inevitable while staring at the oddly beautiful bioluminescent plants."
This is basically a view to what a planet would look like once the amalgamate has taken over the majority of it.
