Fortress: The Tower

The away team find their way blocked by a massive bulkhead. The team report that there is a recessed alcove to their right, housing a pedestal and a contraption wrought in the same black metal as the fortress itself. They believe this device is the key to opening the bulkhead. The leader of the explorers describes it as three upright poles spaced equidistant across the top of the pedestal, with three rings - metal tori - of varying sizes placed around the leftmost pole, the smallest at the top and the largest at the bottom.

The command below will trigger the "Fortress: The Tower" event in Stellaris:

When this event fires, you can choose between these 4 options:

• Place metal rings around the remaining two poles.
• Search for torus-shaped indentations on the bulkhead.
• Rearrange the metal tori on the poles.
• Remove center and rightmost poles from the pedestal.

Stellaris events fire in chains — one event leads to the next. Here is how Fortress: The Tower (leviathans.2131) connects.
