Became Swedish, got War Elephants?

[Mees Henneken]

So as the title says, I got the event to convert from Norse to Swedish and accepted. It didn't say anything about gaining innovations, nor can I find anything special regarding this event online. But I noticed a while later that I was able to recruit War Elephants as men-at-arms. Huh. As you can see from my screenshot I have the innovation unlocked with zero counties in the required region being Swedish (or Norse for that matter), but it's not a visual bug either because I can legitimately recruit them.

I'm far from upset, I love my Swedish War Elephants, but does anyone have any idea if this is working as intended or if it's maybe a hilarious bug?

Norse were actually major ivory traders back in the day, the most significant suppliers of it in northern Europe in fact. Where did this ivory come from? From walr... from the elephants that lived (and still live!) at Kolmården in Sweden.

Ok we got:

- Teleporting armies
- Elephants in Sweden

TELEPORTING ELEPHANTS FTW!!!

Every Swede who has graduated high school knows the story of famed general Hannibal Barksson(*) who attacked the Roman Republic with his elephants.

Hannibäl Bårksström, please.

Hannibäl Bårksström, please.

I'm just going to assume that Bårksström translates to "Storm Boats" and imagine he launched amphibious assaults with elephant-laden longships.

Please, nobody correct me.

It's an alternate timeline where Mammoths didn't go extinct.
