About the names on the stone slabs in Chapter 1 and riddles in general
Strictly OOC.
I didn't want it to make it too hard but didn't expect you to figure this out too early.
Well, not immediately at least.
But our great puzzle solver @{DM Hael} slammed the door on the my nose pretty hard and fast

I certainly hope that Silent "Mister Single Circuit" Giant didn't mean to figure this out IC. Well maybe recognising Sirrith's name though I'm not sure he would even remember that after a good night's sleep. Well maybe he has enough reasons to memorise that name after all.
As a general rule, I would like to remind all of you how I like to handle riddles.
IC-- play your character faithfully!
If you think there's no chance your character would figure out that much, don't write it IC!
If you have a recommendation on a party member's (typically, NPC's) next action think twice how to word it... Or don't word it IC.
OOC-- work together!
Maybe your official
Mensa scores don't rate too high individually but as a group you may brainstorm a few days and come up with a solution that would've anyway occurred to the party's genius (IC speaking).
NPCs have a bad habit of omitting any serious brain activity unless provoked. If you ask if Maul has a certain spell memorised or have any idea what Murkatos should do with his (currently) meager magic assets write OOC and he may do so... IC

Similarly, throw your meta information together (e.g. as players you probably know the resistances and vulnerabilities of all opponents) and feel free to discuss how much of a chance a ranger, rogue, bard or priest of Lirr has to actually have that information from past experience or studies. Someone with undead / chemicals / divine rituals / arms all throughout his background probably knows tidbits others of the same level may not.
Just remember. Metagaming is thin ice. If unsure, ask the DM -- preferably in private if your idea may impose spoilers for others.
I have to confess this game is getting more and more fun as we progress. I dug up my old notes; so old that they predate the year when I bought my notebook to write this adventure (2010). So old that they predate the release of D&D 3.0 (2000). And re-reading them I'll have to adjust the upcoming chapters because I forgot quite some great moments I planned back in my mid teen days. Hope you enjoy playing as much as I enjoy telling this story!
