Nova Aetas is set in the world of Calradia, but in a later period. The Old Medieval World is vanishing. A new era is coming and you, the player, will experience this. Nova Aetas is Latin for A New Era. The main targets are realism & extended gameplay.
Im guessing shields, pikes, bows and Crossbows (And others) can be made here?
Shields, bows and crossbows; yes. Pikes are made by smith.
But aren't shields and crossbows especialy have metal parts on them?
Yes they do, but these weren't created by the blacksmith.
