MC's Shit List
The Lyran Family
For Osian, we have already taken Airi from him, the money he lost from setting that up, made sure he could not get Carly (Airi's mum), collected the 1 million bounty and also stopped him from getting the Vox girls. I am sure that I am missing a few others as well. Finshel was cock blocked from Molly and Kylie (If I remember correctly) by the MC. Finshel is too insignificant to warrant further attention from the MC, and more than likely to stupid and will be caught doing something he should not and will be dealt with by some other party.
Future payback - IMO I would say MC will take both of his daughters and after curing his sister of her illness, she will also for MC. I think the MC will be the future Emperor that the shadowy group is talking about, so of course he going to stomp all over the pipsqueak and his plans.
The Leone Family
Of course he has Kylie, which scuppered Clint's plans.
Future payback - More than likely the other Leone daughter will be a part of MC's harem (I am sure Kylie will enjoy her husband taking her sister and when she has given birth Kylie will raise the child and they will only know them as aunt rather than mother. Again when MC is emperor, the Leone's will have to look to their laurels. At the moment I cannot think of anything truly dastardly.
Fione who currently resides in the prison.
As she is all about Halflings first and only, she will likely be MC's personal cocksleave.
At the moment, I cannot think of who else may have earned a place on the Shit List.
Honourable mentions.
The tribe that want to join with the Amaz. (Cannot remember their name.)
Doubt they will earn a place as will be dealt with at the tournament by MC's Amaz wife. (Again I cannot remember her name. {I am kicking myself for that.
})
I hope you can come up with some decent scenarios for those that shall feel MC's wrath.
