Elp usually typed after somebody has hit H and opened the ingame Wiki.
If you are trying to get help from a tower guard please exit the in game wiki and open your local window, to type help.
If you are taking the time to read this notice you are probably laughing too hard to actually need the help.
If you do die, a Vyn priest or many other priest types can be asked to cast locate soul on you, to assist in finding your corpse.
Thank you and have a nice day!
