Has anyone ever done event chains?

[Albion]

Hey guys, I'm just curious: Has anyone ever done a mod to introduce event chains?
Something like: Event A happens. If player decides B then after a while event D happens but if player decides C then nothing/event E happens.

The search function didn't yield anything unfortunately.

I'm considering to try and create some form of quest or unfolding event that might tell a small story.
It's always easier to check out someone elses work for ideas/inspiration on how to implement it.

If such a mod doesn't exist I'm also happy to discuss options on how to implement something like this and I'm open to suggestions on what kind of event chains might be an interesting idea/story.

The only think that came in mind with that complex structure are the
Mechanoid terraformer event.

The mod is outdated since ages, but still get supported but at the HCSK modpack only. But the modder Rikki is still active.

All other event i saw are pretty simple.
