Looking forward to my first event, but, questions.

What's the relation to control spells? If I cast Control Undead, for instance, how does that work?

Specifically I mean, I'm not sure if it has a duration, or if I would also have to supply my own player for that as well. I suppose it'd be much less commonly usable than creating an undead, but I'm concerned if it presents the same problems with drawing from the small pool of NPCs available.

The same thing applies to dominating a living being, whether it is a troll, ogre, or lizard kin. Be respectful of NPC resources. Control it, use it against the other NPC's, then let it go. Don't hold it post the length of the mod to prevent people from being stuck beyond their shift

Mmkay, thank you! I have one final question...

Would I be able to use a coreless throwing dagger as a small weapon? I heard that thrusting with weapons is generally discouraged because it's easier to accidentally hurt someone, so if I could use a coreless knife that would would make it impossible for it to happen (easier for me than trying to not instinctively stab with a stabbing weapon). If it's not allowed, and all melee weapons have to have a core, could I have the reason as to why? If not it's fine.

No, a small weapon must have a core, and a thrown weapon cannot. They cannot be used interchangeably for safety reasons. You cannot block with a coreless weapon.
