There are a handful of common calls that are not combat mechanics, but used as safety mechanisms during the game.
Safety Hold / Lay On
Any person on an event may call a hold. If a hold is called, everyone who hears it should immediately repeat the called hold and take a knee. No other speech, communication, or action is allowed, unless it is to discuss the purpose of the hold. Once the cause of the hold has been identified, those involved are not required to stay kneeling if they need to move to resolve the issue. Once the issue is resolved "Lay on" is called by the originator of the hold. If it is unclear whether or not the cause of the hold has been resolved, anyone may ask "Is there any reason for this hold to continue?"
For example, someone falls over during combat in a way that may have caused them to be injured and the person they were fighting calls a hold. Everyone takes a knee. Anyone is allowed to ask the fallen person if they are okay and if they need assistance, as well as assist the person. Once the person has been assisted and is either found to be okay, or taken to an out of game area to receive further assistance, "Lay On" can be called by the person who initiated the hold.
Permission for Physical Role Play
Any person may request permission for physical role play. If you want to participate in an action that is not defined by the rules, such as tackling or slapping someone, "Permission for physical role play?" can be asked before the action is taken. The planned action can only be continued if consent is given by the recipient. They may also ask the question back immediately, before game play resumes. The recipient may also ask for clarification of what action is planned before giving consent.
If permission is denied game play must continue within the defined rules.
Descriptive Hold / Lay On
Called only by plot. This is used only to issue a brief description of a scene that the players are about to enter. Players are not allowed to act or to talk to each other but may ask questions to the plot member.
Walking Hold / Lay On
Called only by plot. This is used only on events where there is a shortage of NPCs and plot needs additional time to set up a scene. Players may continue to talk to each other and act, but may not proceed down their current path until a "Lay on" is called. The plot team will try to avoid using walking holds.
Pause for Walkers / Bikers / Car / etc
Any person on an event may call "Pause for [Interruption]," such as people walking, biking, cars or any other similar obstruction. This signifies that there is an interruption and the game is to be paused. All players should move to the side of the road or path and wait for the interruption to pass. The initiator calls the "Lay on."
If a role play scene is moving in a way that you are uncomfortable with and it is starting to push your comfort zone you may raise your hand with the palm outward towards the person or people becoming too intense, and say "slow." If someone tells you to slow, you should tone down the scene you are currently in and not increase the intensity past the current level.
If a role play scene has become too intense and you are no longer comfortable or willing to continue, you may call "cut" while crossing your hands in front of you and remove yourself from the scene. Please take the time you need to recover before returning to game. If someone cuts a scene you are participating in, you may continue without them if possible.
Any person may call "decorum." Literally meaning etiquette, this is used to remind players that conversations should remain in game to not break immersion.
