Ok, Coraldo Hernandez, brilliant though often drunk egomaniacal playboy of House Bonisagus realizes he needs to start showing results in his laboratory work, as no one seems to recognize his innate genius in the way he would like.
SO, he sets his eyes on some sort of hermetic breakthrough.
After a few Twilights, he finds himself feeling the movements of the spheres. He wakes up the exact same time each day. He knows when certain constellations are above him. He decides that perhaps he is being shown the path he needs to follow for hermetic glory by his own somewhat intoxicating magic. He turns his eyes towards the skies. He does not want to extend magical power beyond the spheres above, but he DOES want to interact with them.
He decides to try and work on a new Range: Stars.
His reasoning is that by focusing on those things under the stars by way of the constellations above, he can effect them. The player envisions this as something akin to "Range: Road", and will need to worry about the same issues that such spells have trouble with: how to sense the target, a hefty increase in spell level (+5 magnitude), and potentially requiring casting at night, and not being able to affect those within regios, or potentially underground (unsure of the cosmological implications of that, in truth).
In the words of Coraldo's player:
That said: ambitious, but too crazy?
What do the fine sages of Conventio Forum Ars Magica say with regards such a breakthrough?
