The Second Chamber

Our science team reports that when they pressed the blue button, the chamber resonated with a great grinding sound. A hidden door swung open, revealing a second chamber. The walls of that chamber glowed a faint purple, lighting up a multitude of pictograms that cover every visible surface. There is a second console. As with the last, it features exactly two buttons. This time, one has an engraving of an isosceles triangle, and the other a regular pentagon. It is time to make another choice.

The command below will trigger the "The Second Chamber" event in Stellaris:

When this event fires, you can choose between these 2 options:

• Press the triangle button.
  • Leads to event: Wrong Button
• Press the pentagon button.
  • Leads to event: The Third Chamber

Stellaris events fire in chains — one event leads to the next. Here is how The Second Chamber (astral_rift.1530) connects.
