Idea I had on a whim today (which may or may not have been after killing 53 lions ).

What if upon killing or nature reserving a certain amount of lions, you'd unlock titles by interval? Using the Kill/Sent Away counter on your king's page. As example numbers maybe you'd unlock a title at 50 lions, then 100, then 200, then 500, then 750, then 1000. It's a cool way to add achievement titles and also a fun chance for extremely hilariously edgy badass ones on the Kill side.

I thought up some example titles:
50 lions killed: Gruesome (NAME) or (NAME), Gruesome
100 lions killed: Cold-Hearted (NAME) or (NAME), the Cold Heart
200 lions killed: Shadow (NAME) / (NAME), the Shadow
500 lions killed: (NAME) of Darkness
750 lions killed: Abomination (NAME) or (NAME), the Abomination
1000 lions killed: Angel of Death (NAME) or (NAME), Angel of Death

50 lions reserved: Virtuous (NAME) or (NAME) the Virtuous
100 lions reserved: Savior (NAME) or (NAME), Savior
200 lions reserved: Paladin (NAME) or (NAME) the Paladin
500 lions reserved: (NAME), Giver of Life OR alternate: Legendary (NAME) or (NAME), Legendary
750 lions reserved: Guardian Angel (NAME) or (NAME), Guardian Angel
1000 lions reserved: Arbiter of Light (NAME) or (NAME), Arbiter of Light

Anyway,,, yeah, that's all. I think it's a really cool idea.
