Situation Aspect

situation aspect is temporary, intended to last only for a single scene or until it no longer makes sense (but no longer than a session, at most). Situation aspects can be attached to the environment the scene takes place in—which affects everybody in the scene—but you can also attach them to specific characters by targeting them when you create an advantage. Situation aspects describe significant features of the circumstances the characters are dealing with in a scene. That includes:
• Physical features of the environment (Dense Underbrush, Obscuring Snowdrifts, Low Gravity Planet).
• Positioning or placement (Sniper’s Perch, In the Trees, Backyard). • Immediate obstacles (Burning Barn, Tricky Lock, Yawning Chasm).
• Contextual details that are likely to come into play (Disgruntled Townsfolk, Security Cameras, Loud Machinery).
• Sudden changes in a character’s status (Sand in the Eyes, Disarmed, Cornered, Covered in Slime).
Who can use a situation aspect depends a lot on narrative context— sometimes it’ll be very clear, and sometimes you’ll need to justify how you’re using the aspect to make sense based on what’s happening in the scene. GMs, you’re the final arbiter on what claims on an aspect are valid.
Sometimes situation aspect become obstacles that characters need to overcome. Other times they give you justification to provide active opposition against someone else’s action.
