Yes, the magic system is rather confusing. The translated side materials have some information not present in the main media of TM.

I never read the Tain and the only info I have on Medb is Lancer's backstory, some small stuff I scavenged from GO discussions and her TM wiki page, so I don't know much. But I do look forward to see what you pull off.
