Sorcery (15 points)
Magic is energy. Particularly, the energy created through the tension between the Eidolon and the Umbra, generated when stability and entropy are in conflict. All of the myriad worlds the Grand Stair runs through have some magic to them, and the Gossamer Lords are able to evoke this energy to achieve magic effects of their desire.
Sorcery allows the magician to construct and create spells. Spellcraft is much like in the Amber Diceless Roleplaying game. Spells stored for use require an object to be hung on. Different gossamer worlds allow for different levels of magic.
