Also, this was never made clear to me:

var/area

west_exit

Entered()
usr << name
return ..()

north_exit = .Castle_Entryway

Also, when going into different areas like that, how can you have it so that when you speak in that area on people there can here you?

mob/verb/say(T as text)
world << "[usr]: [T]"

mob/verb/whisper(mob/M,msg as text)
M << "-[usr] tells you: [msg]-"


Thank you, Shiba Arai</<>
