The above link is to a post I made in Jormungand's character thread. I want to integrate the personal vis source into his corpus, as it were. 
I'd like to avoid the legal complications of an external vis source being a seisin of the covenant or a legacy. Additionally, I'd like it to be a reason for Jormungand to research longevity rituals which don't cause fertility. In his case, he is not infertile. He needs to conduct research as to why that is, and see if it can be replicated for other rituals.
What thinkest the troupe?
