This type of sorcerer has the ways of science and magic. using his hand and his brain with the stars above, to create their own magical ways that can give magic a whole new meaning. They are looking deeper to the beyond of the universe. They must prepare to become the protector and keeper of the stars. 

White dwarf

 with this ability you can make a small white dwarf star to use as a light source. this light source can see up to 50 feet. after its use you send the dwarf into the sky to continue its life as a new born star.  This move has 3 uses per long rest. 

Astral shield

As magic from the starlight flows through your body, a magical shield appears in front of you to protect from enemies. This shield has 5 HP. Increases by 5 when you reach level 6. Can't protect against melee attacks. 

Red dwarf

Starting at 6th level, you can make a red dwarf star that's 5 feet by 5 feet. this star moves automatically 10 feet in a line every turn for 1 minute. whoever touches the star is dealt 2d10 fire damage and must make a constitution saving throw. on a fail, that person is blind for 30 seconds. 

T Tauri star

At 14th level, you can create a T Tauri star(it occurs at the end of a protostar phase when the gravitational pressure is the only thing holding it together.) It produces strong powerful winds that can be used as an action to push back everything around you. everyone around you within 50 feet must make a constitution saving throw. on a fail, they take 2d8 force damage and are knocked back 20 feet. on a success, they take half damage. 

Additionally, if you use 2 sorcery points on the T Tauri star, you can absorb the star and create an Astral body armor with 20hp.

The blue star

Beginning at 18th level, you can create a blue star( these stars are found in complex multi-star systems where there evolution is difficult to predict because of a phenomenon of mass transfer, can sometimes end their lives with a supernova.) as a reaction to an attack, you absorb the attack and take no damage. once you do this three times, as an action, you can use 3 sorcery points to make a supernova.(During a supernova stars can change into Two different things.)

Black hole: Everyone within a 50 foot radius must make a constitution saving throw. on a fail, they are knocked prone for 1 minute. 

Neutron star: you send a glowing star 40 feet in front of you and it expands in a 30 foot cone radius. anyone within the cone takes 2d12 force damage. on a success, they take half damage.
