I have made some weapons and armour for the alfr. Dokalfr will wear full plate items. They cannot make chainmail and will wield improved but heavier warhammers and battle axes. The Ljosalfr wear chain shirts and wield swords and spears, both modified to be lighter to keep their speed up. Interestingly a Ljosalfr beats a fully equipped Dokalfr in an arena fight.
Both races have been made large enough that norsemen can buy/loot their gear to wear as it's the only way for norsemen to get heavy armour other than moods. Though I would advise against using alfr armour on any but the most skilled of armour users as it weighs a lot more than vanilla armour.
I've also made dane axes larger and two handed since I noticed that all norsemen would be large enough to wield them in one hand, when the images I can see of their use depict them as being two handed weapons. I'll get the current version packaged up and on dffd soon.
Next up I'm going to try and come up with some metals for the alfr to use. Alfstal is my basic concept: a lighter version of steel, though I'm tempted to split it into two version: Ljostal and Dokstal, the former being lighter but slightly weaker, the latter being heavier but sharper.
EDIT: New version is up.
