Should I be worried if things go awry?
I've bought the module and I'm reading over it, I know there are artifacts and stuff that needs to be collected but I'm worried that my players might ignore them or miss them (which will probably be my fault)
I know places are leveled, so more powerful enemies are in some places but how can I express that to my players without them getting into combat and TPKing?
Also I don't know how I would bring in new characters if theirs die
I don't want to muck it up for them because it's horror and spending 30 minutes arguing over why they died or why an NPC is dead would ruin it
