Like what would happen if the original timeline and the other timelines created by others met

fun fact
shadronia has game night every month with his au selves

Just read the title

The only way timelines can interact with each other is through use of a dimensional diamond

These are extremely rare and give the user the ability to go from one timeline to another

but happens if they do?

Using a dimensional diamond just makes a portal to whatever timeline you want

It basically does the same thing as a regular portal so there really isn't any effect

oh ok

Ahem

?

Look at the object in the figure to the lefts chest.

looks like a solid block with a villager happiness particle effect

Wdym?
