Red, plain door.
After having stepped through the portal back in the Ruins, Vivian, Bree and Martin now found themselves somewhere else entirely. It was a vast, green field, choked full of knee-high, swaying grass. The sky was a bright and distcint cyan color, and there were a sun, much like our own, looming above - judging from its position, it seemed to be about noon in this world. There was a real lack of anything else though, no trees, no wildflowers, no visible wildlife - just grass and hills. Oh, and the yellow-brick road. That's right, there was a road of yellow tiles, with each tile being roughly one foot in width and breadth, laid down just under their feet. They had actually stepped out onto it and were standing in the center of it. Thick enough to let four people wander arm in arm, they still had some space to thesides before they'd step into the grass.
The yellow path slithered and turned, twisted and bent, leading off into the distance. There were two paths, the one forward and the one backwards. Apart from this, there really wasn't much to see right here. Hopefully their navigator would be able to tell them which way to go and begin leading them straight away. It seemed as though they were in luck however, seeing as there didn't seem to be any native creatures or aliens about!
Yellow, plain door.
Meanwhile, Joseph, Sebastian and Ailis all stepped through and entered the world belonging to the yellow door. This was a place of stark contrast. First of all, the skies were covered by heavy, dark grey clouds and a nasty and intense rain was currently pouring down. In addition, the place they stood in resembled a swamp, with many small, boggy lakes, mossy grass and knolls, gnarled trees with dark, heavy leaves and branches... There was no paths or roads here, just marshlands, and at the very edges of it, the trees formed a sort of thick, natural wall that made it impossible to explore or go beyond this mire. To further complicate matters, there was a veil of translucent, white mist rolling in and veiling the world, obscuring long-range vision.
There were many kinds of vegetation growing about the edges of the little lakes, from things that looked like our cat-tails to things similar to hydrogena plants. There were also other, bizarre flora that resembled purple or bright-red lollipops that stuck outta the water. But these flowers all faded in comparison to things on the edge of one's vision. For skulking about, just at the edge of where the fog shrouded as thickets, there were signs of movement. And given that there was no direct or mentionable winds blowing at the moment, one could only assume that this was the movement of some local entities...
In this stormy quagmire, the three explorers should probably prepare themselves, and travel with caution - less they run into something they might not get along with...
