I’d like to see the text displayed in the room when a character teleports to be non-descriptive about how that character arrives or leaves, leaving it up to the player to decide how detailed of an entrance or exit they desire.
Currently, a character always “appears in a flash of light”. I read this as taking the notion of “teleportation” quite literally, as if my character (and everyone else in Sindar) can effortlessly zap themselves around at the speed of thought. That doesn’t really mesh with my notion of how my own character works! I rather envision him as simply and mundanely walking around town. When I-the-player teleport him, I see it more like a jump-cut in a movie: the hero leaves their house and immediately arrives at their office, skipping the understood commute for narrative convenience.
My proposal involves replacing the messages with “[Character] arrives” and “[Character] leaves”, or something similarly anodyne. Players can choose to leave these messages as-is, or follow/precede them with poses putting more detail into how they arrive. To be clear, I do this already, but the effect is a little jarring, looking like a weird space-time skip:
Halstrick appears in a flash of light.
Halstrick pads in, sipping his coffee. "Good morning."
Replacing that first line with a much more neutral message, and letting players fill in details as desired, strikes me as both more IC and an incentive to role-play a little bit more.
