So, I'm in Soltheim a very short distance southwest of Skaal village, and I'm standing in front of a boar named Bilgemuck. It's offering me an option to talk to him and give him a gift, but I don't have a gift to give him. Can anyone explain what this is about?

Has to do with the Thirsk quest

so can i give the boar any food or does it have to be something specific?

It has to be meat. Find Thirsk Mead Hall and you'll get the quest there.

Anyone else find it creepy you can feed that boar it's own kind?

Meat. After that, it's pretty straightforward.

"Bilgemuck!" I just love their voices.

In my game i cant take him to the chieftain... Whenever he enters thirsk he immediately exits... And i eant my damn riekling follower!

He isn't supposed to enter the hall itself. He has a little pen to the side of the hall. That's where he's supposed to go.

I am still bummed I ran into the Nords before I even saw any Rieklings...did their quest and re-took the hall...
No Reikling followers for me on this char...
