 ### Events
 
 Quest scripts are event based, the following events are currently responded to by the Lua parser:
+
+All event functions are passed one argument: an event table.
+For NPCs the table will always have 'self' as the npc.
+For Players the table will always have 'self' as the client.
+For Items the table will always have 'self' as the item and 'owner' as the owner of the item.
+For Spells the table will always have 'self' as the spell.
