The images are an example. The Quest Mod only provides the option for adding a data-driven quest system to entities. No interactions are added to villagers unless a Mod or Modpack maker states so in their files.

Quest Giver provides the option for adding a data-driven quest system for modders and modpack makers.

It's design and function is based on the Quest System used in the Feywild mod.

With the Quest Giver Mod you can add Quest Lines to Entities/NPCs.
Each Quest Line has multiple Quests.
A Quest Line starts with a Root Quest wich gives the Option to Accept or Decline.

Each Quest has a Start Window and a Task.

If the Task requirements are met a Complete Window will pop up when interacting with the Entity/NPC again.
