shaper's stronghold

How do you make them appear on your atlas in std?
I killed shaper and uber elder but nothing changed, are they league only?

There are four of these initially on yellow maps. Upon completion, each one will appear on red maps. Upon completing these, they will have a chance to randomly spawn when Shaper Influence is created. It's a percentage chance whenever a Shaper influence spawns (to defend against the Elder) that it'll be a Shaper's Stronghold. Its tier can't be guaranteed but you can restrict it by controlling the position and level of your Elder influence.
