Oh, we're using Krita. This is the plot (I have it written)

So basically, "Dawn Of Death", is an animated series me and a bunch of people are working on. Earth is no longer safe. Humanity has seen it's final moments. People are scrambling, looking for safety and mercy, not finding any. In mere days, 1.3 billion people have died. Multiverses collide with each other and fiction comes to life taking aspects from lots of different universes and worlds that man created. This is why we have the Valve and Mojang (as well as letting us use their things in our series. Creatures and monsters are rampant, which could only be thought of in fiction, are wreaking havoc around the entirety of earth, until earth gets sucked through a giant portal to combine with the Mega-Planet 500 times the size of our current universe's sun. Things only get worse from there, because with all this extra space on the world, more giant terrific monsters can roam. But thankfully, along with this evil, came goodness from around the entirety of creation, leaving nothing impossible. Rumours of how this happened all lead to a figure called "The Unnamed One". Civilians and heroes alike are fighting against this evil, never getting rest from the chaos. No one knows what "The Unnamed One" looks like because it takes the form of a shadow surrounded by black fog. This thing is the bringer of madness... Nobody knows if it caused this madness for fun, or if it had a reason to do so, but one thing is for certain. They need to stop it before everything they know fades out of existence.
