One of the smartest things Star Trek Adventures does is recognize that a starship is more than its bridge crew. The captain, first officer, chief engineer, science officer, doctor, and security chief may get the spotlight, but the ship itself is full of people: Junior officers, specialists, technicians, nurses, shuttle pilots, barbers, security teams, stellar cartographers, the person in engineering who knows the plasma manifolds better than anyone else aboard.
Those characters matter.
In a lot of RPGs, anyone outside the main party becomes scenery. They deliver information, get rescued, or die to prove the danger is serious. Star Trek has certainly used that trick before, but that’s why I love STA’s supporting characters.
Supporting characters let players step into different roles when the story calls for it. If the captain and senior staff remain on the ship, someone can play the away team’s young geologist. If the chief engineer is busy coordinating repairs, another player can bring in the Bolian warp specialist crawling through the Jefferies tubes. If the doctor needs help in sickbay, someone can play the nurse who has seen three crises this month and is very tired of heroic nonsense.
This changes the texture of the campaign. The ship stops feeling like a backdrop and starts feeling like a community.
personnel. What was great at that moment is that these were security officers the players had taken with them before, they had names. But in that moment, with them playing characters who weren’t their primary characters, I felt a little less guilty if the entity ended up killing these officers in a dramatically appropriate way.
The easiest way to make these characters matter is to give them names before they are needed. Do not wait until danger appears to introduce “Security Officer #4.” Put Ensign T’Rel on the bridge during a quiet shift. Let Chief Petty Officer Marquez complain about the replicators. Mention Lieutenant zh’Raal running diagnostics before the anomaly arrives. Once players recognize these people, they become part of the emotional landscape of the campaign.
In a campaign I ran last year, an entity was loose on the ship, and while the main characters were trying to repair the damage she had done, we switched over and the players took on the roles of security personnel. What was great at that moment is that these were security officers the players had taken with them before, they had names. But in that moment, with them playing characters who weren’t their primary characters, I felt a little less guilty if the entity ended up killing these officers in a dramatically appropriate way.
Let supporting characters have small areas of expertise. One knows the old Constitution-class refit systems better than anyone. One grew up near the Neutral Zone. One speaks a little Cardassian. One has family on the colony the ship is trying to save. These details do not need to dominate the story. They just need to give the character a reason to exist beyond waiting for tragedy.
You can also use supporting characters to shift perspective. A lower-decks session can show how the senior staff’s grand decisions affect the rest of the ship. A diplomatic crisis looks different when you are the junior officer preparing guest quarters for three hostile delegations. A battle feels different when you are sealing bulkheads, moving wounded crew, or trying to keep frightened civilians calm.
Most importantly, do not treat supporting characters as disposable. They can be endangered, injured, promoted, transferred, or even killed, but those moments should carry weight. Their purpose is not to make the main characters feel important. Their purpose is to make the ship feel alive.
When supporting characters matter, the campaign gains depth. The players are no longer protecting an abstract vessel with a hull rating and a weapons score. They are protecting a home full of people they know. The ship becomes a society in miniature, and every mission becomes a little more personal.
