The question of "Who are you?" is an integral part of any roleplay, and Astronomika is not any different. Before you can participate, you must create the character you play as. You must define who they are, what is their personality, what their backstory is and how they behave. You must also build them with the tools given at the following section. Strengths, weaknesses, skills, perks, abilities... all must be taken into a consideration. Everything must make sense for the character you are creating, even if it might not be 'best' when it came to things such as combat or other forms of expertise. This term, known as min-maxing, is frowned heavily in any roleplay game and in Astronomika especially. A character sheet that tries to game the system or min-max in a clearly blatant way (trying to pick only strengths so that they cover any possible weaknesses) will get your submission rejected immediately. In a roleplay such as this you cannot be best at everything, so you must choose your strengths and weaknesses in a flavorful way that makes sense for your character.
Indeed, when it comes to the character sheets submitted there are few things appreciated over all else, which will get you that much closer to being one of the characters and players chosen. These things are innovation, creativity, uniqueness and integration to the lore. If you have any questions regarding the backstory of the world or need further explanation about some of the terms and concepts mentioned at the rulebook, do not be afraid to ask the GM. He will be happy to provide further information to help you build your character.
So, without further ado, the following part of the site teaches you how to build your character. The last sub-page will provide you with an example sheet to give some sense of how it should end up looking.
And speaking of how things look, there is a modest wish from the GM of the roleplay. Any faceclaims for characters should have either white or transparent background and feature the character in question at least from the waist-up. Full-body pictures are even better. Best thing would be if the character has other pictures of them too, ones that could be used as sort of 'Event CGs' as in visual novels or what-not. This is not a necessity but it will make the job of the GM a whole lot easier when it comes to presentation and various other things concerning the roleplay.
