Unique EVENT?

I'm currently looking for an event that can be implemented in a computer game if possible. Conditions:

• uniqueness

• Minecraft (feasible)

• Fantasy / Middle Ages / etc.

• Not modern

• Nothing exhausted (drops…)

And you want the others to give you their ideas now because you asked so nicely?

No, no ideas / concepts. I actually hoped for a nudge, an idea / a word. If I have been rude, I'll say Sry

Sry, that's a contradiction in terms
