Shielded worlds: Event types

[Wolfgang I]

How many different events are there for shielded worlds?

Spoiler: Shielded world event spoilers

I have gotten a 5 star admiral, FE ships and a group of void clouds before. Are there more? On a sidenote the void cloud event is rather underwhelming.

The FE fortress I inherited over the shield world was not impressed.

In my most recent playthrough I got some FE ships from two shielded worlds.

In an earlier playthough I also got the voidcloud event. By chance it occured together with the start of the Unbidden invasion, so it seemed like I unleashed the Unbidden on the galaxy by taking down the shield.

i regularly find shielded worlds early on but with no annomolly - i dont think AI got there before me because it was so early i was only a 3star leader.
Do some just do nothing?

There is a Special Crystal Entity System with a shielded world that gives 8 physics Research, but does not have the anomaly. For the Event you Need one inside the borders of an FE.
