Kyle - see Lahr's list. Lahr - if it's a Helga/Lek post I don't have a problem with you doing anything on that front that's personal character development. But I leave it to you and Kyle to work out if you're going to use her or one of your other Security NPCs rather than say Lt. Bailey. I say liaise cuz there might be something Kyle needs a specific character to do rather than there being a tag to Security and whomever has a Security NPC jumping all over it like I did with the nurse coming down to fix up the prisoners (although I didn't give a name, it was just some random on the desk, and it didn't really affect the flow of the story but allowed Medical to get a post in.)
You're both seasoned players, you're savvy enough to work this out yourself. Also remember we have Zavrol Gohun who as an APC should always be given priority over any NPCs please.
Personality traits would be useful yes... this goes for anyone with established NPCs.
Like I say I'm hoping to sort out all the NPCs, get it all into one doc, with the established and oft-used ones put on the main roster (e.g. Gianetti for Engineering)
My NPC's at this time are intended mainly for flavor not sustenance. Ie So when Lek or Kyle calls up Helga... she'll be doing random duty patrol with her partner - but not actually involved in the action of the mission unless the Captain or Kyle tags them in.
However, if we get into the thick of things and people aren't posting... then yeah I may offer to stick my nose in a bit more to move things along. However, I will run this by the Captain first before doing anything.
