Eep!
I really like that the module starts with the bad guy scrying the PCs. The Lizard King is a smart and proactive foe. Like many 1e modules it does have some odd things in that I will ignore but it also seems to have a lot of treasure. I was surprised to see a sword +4 defender and just a lot of magical items in general even before they get to the meat of the module.
Well, they may well need to survive...

Cheers!
