We were able to take several different viewings from this world, and we discovered that it not only is significantly larger than our Earth, implying a higher gravity, but it is volcanically active the whole world over. As interesting as Lava-world would be to a volcanologist, we sadly had to cross it off the list of viable alternate worlds to migrate to."
