You come from a line of stargazers and explorers who delved deeply into the darkness beyond the stars. In touching the void, the void touched them, and your mind, spirit, and body yearn to span the gulf between worlds.
Class Skill: Knowledge (nature).
Bonus Spells: unseen servant (3rd), glitterdust (5th), blink (7th), call lightning storm (9th; dealing fire damage, damage increased outdoors at night), overland flight (11th), repulsion (13th), reverse gravity (15th), greater prying eyes (17th), meteor swarm (19th).
Bloodline Arcana: Whenever you cast an evocation spell, targets that fail their saves are dazzled by tiny sparkling starlights for 1 round per level of the spell.
Bloodline Powers: Your skyward gaze and communion with the heavens focus and enhance your magical talents.
Minute Meteors (Sp): At 1st level, you can summon a rain of tiny meteorites as a standard action to fall in a 5-foot column, 30 feet high, with a range of 30 feet. The meteors inflict 1d4 points of fire damage + 1 per 2 sorcerer levels. A Reflex save negates this damage. The save DC is equal to 10 + 1/2 your sorcerer level + your Charisma modifier. You may use this ability a number of times per day equal to 3 + your Charisma modifier.
Voidwalker (Ex): At 3rd level, you gain low-light vision and resist cold and fire 5. At 9th level, you no longer need to breathe, as if wearing a necklace of adaptation.
Aurora Borealis (Sp): At 9th level, you can create a sheet of cascading colors. This power acts as a wall of fire, but it inflicts cold damage and does not radiate heat. However, one side of the aurora designated by you fascinates creatures within 10 feet, up to a maximum of 2 HD of creatures per sorcerer level. A Will save negates this fascinate effect. The save DC is equal to 10 + 1/2 your sorcerer level + your Charisma modifier. You may use this ability for a number of rounds per day equal to your sorcerer level. These rounds do not need to be consecutive.
Breaching the Gulf (Sp): At 15th level, your caster level is increased by 3 when casting spells of the teleportation subschool. In addition, once per day you can teleport a single creature within 30 feet into the void of space if it fails a Will save. The save DC is equal to 10 + 1/2 your sorcerer level + your Charisma modifier. The target can attempt a new saving throw as a full-round action each round to return. While trapped in the airless void, the target takes 6d6 points of cold damage per round and must hold its breath or begin to suffocate.
Starborn (Ex): At 20th level, you gain immunity to cold and blindness, and you can see perfectly in natural or magical darkness. In addition, you gain fast healing 1 when you are outdoors at night.
