d20 Future: CODEX GALACTICA
Space exploration for the Mana System is based on their development of new advanced arcane sciences. Crystal spheres that contain the powers of crystal balls and illusion spells are used for recording and serve as databases of relevant information. Using magic a person can access the information on this devices and work them as computers. A sky ship can be equipped with with “spelljamming helms”. Ships powered by spelljamming helms are capable of flying into not only the sky but into space. With their own fields of gravity and atmosphere, the ships have open decks and tend not to resemble the spaceships of science fiction, but instead look more like galleons, animals, birds, fish or even more wildly fantastic shapes.
In game terms: For a Spelljamming Skyship use the same stats as a ship of the same size but all items will be magical or medieval in their execution. Laser cannons will be magical energy catapults, engines will run with sails, sensors will be crystal balls with remote sensing. Non-etirans will have a -8 penalty using this equipment, -4 for the apparent different in PL and -4 for the alternate technology.
