I was reading Analog Science Fiction, an E-Magazine, and I read about a good planet.
Picture this: Once you pierce the thick cloud layer of the planet, which is grey and foreboding as far as the eye can see, you take in the full image around you. For the most part, it is flat, with the exception of a number of hills- because they were certainly not mountains- dotting the landscape. The ground is the color of old cement, and looks to be made of the same material. On your starboard(right) side, is an inland sea coated in a thick layer of kelp/algae on the surface. Your atmospheric sensors on the ship read off temperature in both Celsius and Farenheit. The planet is cold, with an average temperature of 36 degrees Farenheit. Another sensor, which gathered information from your descent into orbit, displays the acceleration due to gravity on the planet. 4.2 m/s^2. Significantly less than Earth's, but not as little as the moon. And finally, as your ship touches down, the most complicated sensor on your craft reads off the chemical composition of the atmosphere. Enough oxygen, about as much as can be expected in mile-high conditions on Earth. Carbon-dioxide levels, normal.
Welcome to your new home.

On the topic of aliens, I was thinking an intelligent species, but doesn't get introduced until later in the Roleplay? And perhaps they are somewhat ruled by instict. Ex. A species with a developed language, culture, etc. Yet, it runs some facets of society are ruled by instinct such as leadership.
EDIT: Grammar. Word placement.
