NPC's in Grotto Arena

[PanamaLane]

So consider this a question/suggestion. Why are their NPC's in the grotto Arena? Do they serve the purpose of witnesses? Can they be removed so that when spell casters do battle they don't consistently end up getting shot or accidentally murdering a worker? I'm pretty sure each time an AoE hostiles one of these NPCs it leads to having to get a DM for a res etc. which is probably annoying for DM and PC alike. If they are there for a reason, can they somehow be put on subdue or in some other way be prevented from murder? Thanks!

I agree with this wholeheartedly
