OnModuleLoad
From NWN Lexicon
[edit] OnModuleLoad
The script attached to this event fires when the module is first loaded. This is a good place to initialize any variables that need to be initialized.
[edit] Trigger
When a module is initially loaded.
[edit] Remarks
For 1.60+, for new modules a default script called x2_mod_def_load will be put in this event hook, which is required for Use Magical Device settings to be set, as well as other module settings. This is not required, however.
