I have a priest turned necromancer who has used his semen in in his spell casting. The setting is 1628 Ireland, but the necromancer is English by birth. He was highly educated and is extremely arrogant. My question is: what would he call his semen? I am especially hoping for a term that would not be understood by someone with a poor education. I have googled and wikied, but haven't found anything useful. I know about the term 'seed,' but that seems too common for this character and too easily understood by the peasant who overhears him bragging.
Thanks in advance!
