As Someone who has asked OOC and seen several responses to others asking the same, the answer seems to range from "Wait, there's a codified Lex Magica somewhere?" through "Well, there was a listed version that never made the transfer onto this site" to "Sanctum and Sigil is your best bet"
What's your response, West, to anyone trying to hunt down what to read to learn the Lex Magica of Sacramento?
