Banning the somewhat popular Duke of Ikalak who got to appoint all of their lords didn't help Ikalak.
Considering you repeatedly broke the laws regarding appointing people who already had a position, it's not a surprise that you got banned. So congrats on bringing down Ikalak using internal conflicts. That kind of thing is completely opposed to the spirit of this island, which is about working together as a realm in constant warfare with other realms
without politics. *slowclap*
