Bat teeth, vampires, wolves, and werewolves.

There are bats, bat wings, bat meat...
There are boar tusks, bear teeth...
BUT NO BAT TEETH.

Why not implement bat teeth, a so-so curio, that can be wore by a char or maybe it's a usable.
Also implement blood, when you kill a hearthling, you can drain his blood to buckets.
Then, if you wear the bat teeth or maybe use it, and drink some blood, you can gain a buff called "vampiric strength", which increases your agility by xxx for some period of time.
Or perhaps the blood drinking can help increase your SHP, this should probably not be allowed during fights though.
Also, if someone is in vampiric state and are killed in battle, their soul become restless and can not enter the Valhalla regardless of their stats.

Or maybe as such, when you use the vampiric power, your agility and maybe other stats increase for 3 ingame nights and decrease for ingame days.

Similarly, Jorbar can implement wolves, then one can wear wolf skin and eat some hearthling meat (cannibalism), one can gain "werewolf power" which increases str and con.

Maybe both can let a hearthling be able to use "run mode" to walk without spending extra stamina in forests, and use sprint mode without extra stamina in grassland.

I think it's doable, since Jorbar has this Valhalla thing which is mythic, and I think Nordic have tales of vampires and werewolves too.

Speaking of nordic tales... My father once told me of an old norse tale with a restless zombie who couldn't be killed unless you dug up his grave, and he would frequently appear to torment passerbys. On a particular night a man kept fighting and fighting the zombie without giving up, so he appeared and snatched the man's sword only to disappear with it. Angered, the man sought out the dead man's burial place, finding his sword laying beside a grinning corpse.

sure, have dead hearthling corpse stand up and become restless zombie randomly. killing such zombie yields zombie hide, zombie meat, etc.
