Once again this isn't the first time that I've talked about using G3 Hall of The Fire Giant King for an old school pulp heroes or Supers OSR game campaign jump point.But I'm about to subvert everything about this module. First of all this whole module is going take place in Iceland or Greenland. I'd probably use Greenland because of its remoteness & incredible Geology plus its volcanic activity. This volcanic activity leads straight into the gates of Muspelheim itself! Make no mistake that Snurre, the Fire Giant King is in fact royalty of Eldjötnar or Eldthursar, Eldþursar—"fire giants". The realm Muspelheim ruled by Surtr with his consort Sinmara.
Surtr has been waiting eons to draw his bright blade & slay his mortal enemies battle against the Æsir, and the major god Freyr of the Vanir. Afterward, the flames that he brings forth will engulf the Earth.
"According to the Ragnarök prophecies in Snorri Sturluson's Gylfaginning, the first part of his Prose Edda, the sons of Muspell will break the Bifröst bridge, signaling the end of times:
In the midst of this clash and din the heavens are rent in twain, and the sons of Muspell come riding through the opening. Surtr rides first, and before him and after him flames burning fire. He has a very good sword, which shines brighter than the sun. As they ride over Bifrost it breaks to pieces, as has before been stated. The sons of Muspel direct their course to the plain which is called Vigrid.... The sons of Muspel have there effulgent bands alone by themselves.The etymology of "Muspelheim" is uncertain, but may come from Mund-spilli, "world-destroyers", "wreck of the world""
This means that that G3 Hall of The Fire Giant King is a major Summer pulp or comic book cross over event. The warriors of Eldjötnar are going to out for the boiling blood of PC's to help bring out about the end of the world!
Snurre, the Fire Giant King is in fact royalty of Eldjötnar & he's got Chaos cults of human dupes worshiping his kind & acting as human asset support. PC's are going to have their hands full with fire witches & the like.
If they lose then your you are going to giant kind making huge comeback as the gods & giants duke it out in one final showdown. Is the human race going to be a major factor in stopping the carnage or spectators for their own demise?
Surely there's no Arthurian connection here at all? Well actually there are several items from Arthurian lore that were key parts of Arthur's giant slaying exploits within the Welsh mythological traditions.
The Timeless Myths website has a solid list of artifact resources that could present a group with several key side quests for giant slaying side adventures for artifact recovery.
G3 Hall of the Fire Giant King by Gary Gygax is a killer adventure in a real need of PC pulp heroes.
I am the giant Skrymir by Elmer Boyd Smith
All of this ties into two possible Arthurian connections for the tales of both Tom Thumb & Jack The Giant Killer! This a great starting point for a familial origin of a PC's possible powers or mysterious family connections to the events of G3!? G3 Hall of the Fire Giant King by Gary Gygax is wicked adventure with a few twists & tricks to it. Including the reveal that the 'Drow' are behind the whole thing. Surely this going to invalidate the whole mythological twist the adventure?! Actually it won't! The realm of the Dwarves & Dark Elves are very close to each other.
"Niðavellir/Svartálfaheimr, the home of the Dwarves, who are also synonymous with the Dark Elves ("Dökkálfar") and Black Elves ("Svartálfar")"
G3 has some very heavy handed mythological connections & possible old school connotations for a party of adventurers! The events of G3 could put a group of heroes in the cross hairs for a war of incredible destiny! Especially when the manipulation of events is revealed.
I heard the bitching about modern fire arms & equipment being thrown into a classic TSR novel & given the damages I saw in Jason Vey's Adventure! rpg I see little effect really. After giving G3 Halls of the Fire Giant a rereading I feel that many PC's will have their places in Vallhalla assured!
