Mars is the place where FrostPi Forjaekkal is possibly from, due to her being part Martian. It is currently ruled by Queen Leopa. Note that this is not the Mars from the solar system of the normal universe, but is the Mars in an alternate universe, although being not very alternate. Also note that it is not the Roman god of war, Mars, even though those related to either Mars have similar qualities.
Mars is inhabited by Martians. They look like humans, but they have ears like elves, and the full-grown ones have antlers like moose. They are also noted for having orange skin to blend in with their surroundings. However, that skill is not used much anymore, due to civilization being built.
Mars is very, very red.
