Well depending on your interest there are many 1 x 1 I can come up with. *is new here too*
One of the one on one I would like to do is angel(or bird folk/or harpies/or phoenixes choose your preferences.) with merman folk.
The idea is following the mermen folk cannot live with out water touch for more then a hour. While the bird folk cannot survive with out air. The only meeting place where those two ever could meet is the surface of the sea. They dislike each other strongly, as it happened more then once in the past that the merman drowned a bird folk and the birdfolk has let the merman dry out to death with out the touch of water.
The problem is that they share the same living space a mounting cliff that goes high up and deep down. living in the respective air/water part of it. Other details can be figured out depending on what each of us like. ^^
Well this is just a idea I really would like to do. The story would obliviously be one bird and one mer interacting maybe friendship is born? There was a storm and one got saved by other? Curiosity drive them to meet.
