If that is the wish of your leaders, then so shall it be. I will react to all IC interactions as the Nouvellians would. 

So, think of yourselves as Imperialist Europe, and myself, as Africa, Asia, South America, India, etc. I am at the mercy of the decisions of your races. If the Ethereals decided that planet Nouvelle is of interest to them, then so be it. If the Eternal Union wishes to institute such a coupling with the people of Nouvelle, then that is at your discretion as how to achieve such. 

I will give you all some food for thought. The city of the Gods, to the northern pole of my planet, is a rich cultural history of the planet. It in a sense, describes the very beginning of time for the people of Nouvelle. How they got there, who brought them there, why, and so on. Think along the lines of Stargate, or ancient Egypt with the hieroglyphics. The Nouvellians are from Earth, but from a long time past. The were once humans, but, as time progressed, they evolved into a divergent species. The "Gods" who brought them here, are gone, or, at least not known yet. They took these primitive humans from times past, and brought them to far off world to do what they needed. Be it science, slave labor, or perhaps wishing to spread life about the galaxy. 
You as the other players, have the opportunity to develop how you see fit to use this. Perhaps you wish to convince the people of Nouvelle you are the Gods. Or, that the Gods have abandoned us, and you are here to uplift us into the knowledge of the future. You decided if the ancient hieroglyphs depict your people, or something different all together. Perhaps you wish to change these glyphs to better suit your needs and ambitions, the choice is yours, and my reaction will be true and honest, based off of whatever comes my way, good or bad.

I am excited. Lord Duck, and all other players, you do not need my permission to go ahead with your plans, simply put forth IC'ly, and we shall see where it leads us.
