WOW Power Leveling: You have given no chance for the other parties to rescue the child
DON'T write out a conclusion of a scenario without collusion with the other players in your scenario.
"The babe was placed on the alter. Jeqon lifted the dagger and consecrated it to Innoruuk. Testing the blade he made WOW Power Leveling a clean cut, spilling red blood. The infant squalled until its heart beat no more."
Well, well… there, you've given no chance for the other parties to rescue the child, and very possibly put an end to that role-play scenario.
"Arawyn fired the arrow and watched with satisfaction as it flew true to its mark and pierced Koumi's throat. She grinned evilly as Koumi clawed at it as she fell over dead."
Think that the player of Koumi might object?
DON'T use the knowledge that you gain from reading other's off-line stories if your character would not have any reason to gather that knowledge.
For example, if two druids had a secret meeting in Sure fall Glades and your character is a Cleric of Innoruuk… your character would not be privy to what they said to each other.
Finally… whether in-game or out, DON'T get too emotionally involved with your character and the role-play. If you ever do find yourself in that situation, take a step back.
A few days off the game or the role-play might be needed. Remember that it is a game. You really aren't a wood-elf.
