In the original incarnation of what I think of as “The Goldvale Module”, Ema along with Skip & Phil all existed as a love triangle and were humans. Most of their details were otherwise the same plot wise, waiting for players to stick their noses into the business of these 3. Ema became problematic when she tasked that party with a quest to get the fertility potion made by Phil, who needed some human blood to make it work. Instead Ema cheated and used pig's blood, a baby was born, suspiciously rapidly, and it became sort of an anti-Christ. This is not likely as an outcome for the second time are since the current players mess things up in their own special way.
