This is a Shroud event, so you can randomly get this option each time you visit the Shroud. Note that your chosen candidate can die from this even if the choice is green.

Also if you have a Covenant, there's another Chosen trait for the covenant type. This comes as a random pop-up, and your candidate cannot die from this.

You can have both chosen traits, though not necessarily on the same leader.

Nope, its still there:

In fact there are now the normal chosen trait, then there is also a chosen trait for each shroud entity.

You can stack both on the same leader too although that might be a bit of a waste as the 2nd has different effects for each leader type.
