Why keep playing after the final boss?

Me and my friends made a Valheim server and absolutely fell in love with the game. We have a really nice base, tons of stuff, and we all have our own unique houses. It's been an awesome place to hangout with the boys, especially since we're all in college and have moved away from our high school town.

But I'm worried it's coming to an end. Tonight we're gearing up to fight Yagluth. I'm hyped, for sure but also really sad because after that there's just one boss left. No more late nights, random brawls, dungeon delving, and questionable builds.

What reasons do the community members have to keep playing? What keeps you guys motivated to keep booting up this Viking heaven?

Edit: I didn't expect so many replies, Thank you guys for all your awesome ideas, words and suggestions! You guys are the best! My hope has been restored in continuing our adventures in Valheim! All your ideas are awesome, and I can't wait to pitch them to the boys! This server has meant alot to me lately. Everyday we just get older and I know that one day there will be a last discord call. But we gotta keep up the fun while it's here. Thank you guys so much
