Scenario
An opposing duo character is KO'd within 8 squares of a friendly Nekron. The Blackest Night SP is activated.

The duo is turned to their last click and "revived."

Nekron's controller gives them a power action to use Split. Nekron's controller swaps out the duo with a replacement character(s).

Question
Per the wording of The Blackest Night (last line), would one or both replacement characters be removed from the map after the action resolves?

I think it was ruled that you can't give an opposing character an action to split. Not sure where though

One line is being added to the rulebook to cover some oddball situations. As of today, you are only allowed to replace characters if the original character is from your original force. No more using Mind Control to force a replacement on your opponent – sorry!
