Buying and selling feature implemented (kinda) alongside with the conversation feature.

Transaction with merchant required Ogre Core currency, that you can get from adventuring, slaying Ogre or doing quests.

The goal with key NPC is to giving them a personality, giving them a background story, that gives players a drive to do related quests.

Say hi to our first NPC ever, Wawa the travelling merchant!
Wawa will not only buying and selling stuff, but she will overwhelmed you by hoping around, greeting you from a far, and ripping your Core.

I would never thought that implementing buying and selling system will be a pain
