Retrospective: The Glacial Rift of the Frost Giant Jarl

In the early days of this blog, I wrote a Retrospective post about Against the Giants, the 1981 compilation module that first introduced me to Gary Gygax’s famed G-series. That post focused less on the individual modules themselves than on my memories of discovering, playing, and refereeing them. There’s nothing wrong with that – Grognardia has always been as much about reminiscence as analysis – but it did mean that the constituent adventures never quite received the attention I think they deserve.

That’s why, in February 2023, I set out to remedy this oversight by writing a series of posts dedicated to each module in turn. I managed to complete only the first installment before the effort fell by the wayside, for reasons I can no longer recall. With this post, I hope to resume that series and finally give The Glacial Rift of the Frost Giant Jarl an individual consideration it merits, followed by Hall of the Fire Giant King next week.

First published in 1978, module G2, Glacial Rift of the Frost Giant Jarl, occupies the middle position in Gygax's Giants Trilogy, itself the lead-in to the even more celebrated D-series. Consequently, G2 has long been overshadowed by both its position within its own series and the looming presence of what follows. Taken on its own terms as a discrete module rather than simply as a bridge between modules G1 and G3, G2 deserves more recognition than it typically receives. It is, if nothing else, a terrific expression of Gygaxian adventure design, offering a tightly focused, environmentally distinctive, and surprisingly open-ended scenario for high-level (9th–10th) play.

The module’s premise is simple: following the defeat of the hill giants in the previous scenario, the player characters are tasked with continuing the investigation into the source of recent giant-led raids. Their next destination is the icy domain of the frost giants, located high in a forbidding mountain range. What they find there is an immense rift in a glacial plateau, honeycombed with caves and tunnels, and populated by the violent and hierarchical society of the frost giants.

From the outset, Glacial Rift sets itself apart with its setting. The rift is not merely another dungeon, but a semi-natural, hostile environment that actively contributes to the module’s sense of danger. The cold is not just flavor text; it informs the monsters encountered (remorhaz, winter wolves, yetis), the terrain, and the general tone of the place. There’s a starkness to the rift that evokes the unforgiving nature of the mythic North, a realm of elemental cruelty, barbaric strength, and ancient, unknowable powers. There's also something almost mythic in the Jarl’s domain: a vision of primitive kingship, drawn more from Norse sagas than from the usual pulp fantasy tropes, where authority is measured by might and the feasting hall rings with the howls of dire wolves.

Structurally, G2 is more interesting than it first appears. The rift is split into two levels: the upper level consisting of cave-like lairs and animal dens and the lower level home to the giants’ halls, guard posts, and meeting places. Unlike many early modules, G2 is decidedly not linear. Its design encourages infiltration, observation, and guerrilla tactics as much as direct confrontation. A cautious party could spend several sessions simply gathering intelligence, probing defenses, and slowly unraveling the nature of the giants’ organization. Conversely, a reckless party might find itself quickly overwhelmed. It’s a sandbox in miniature, where the players’ tactics genuinely matter. 

Like its predecessor, Gygax naturalism is on full display here. The frost giants are not simply bags of hit points awaiting extermination. They're part of a brutal but functioning society, with guards, servants, prisoners, and even non-combatants. Gygax includes giantesses, young giants, and slaves, all of which contribute to the sense of this being a "real" place that operates according to a certain logic. This forces players (and referees) to make choices. Do the characters kill everything they encounter? Do they parley? Do they seek allies among the captives? For a module that, when it's remembered at all, is remembered simply as “the one where you fight frost giants,” G2 contains a surprising amount of nuance.

Gygax’s authorial idiosyncrasies are on full display throughout the module. His monster choices, like the remorhaz or the white pudding, show a willingness to embrace the weird and unexpected. His treasure hoards are filled with oddities, while his trap placement is often arbitrary but memorable. His prose, full of abrupt capitalizations and florid phrasing, imparts even the most banal descriptions with contagious energy. Glacial Rift is thus unmistakably his work: unapologetically high-level, at times unfair, even cruel, but always imaginative.

That said, the module is not without its flaws. The maps, presumably drawn by Dave Sutherland (there are no credits), can be difficult to read, especially given the three-dimensionality implied by the rift’s vertical layout. Navigation can become a chore unless the referee is particularly adept at spatial description, which I must confess I struggle with. Some encounters do feel a bit like filler – yet another cave, yet another pair of frost giants – and the rationale for the party’s presence here (to follow up on the events of G1) does feel thinner than that of either of its brother modules.

Even so, The Glacial Rift of the Frost Giant Jarl more than stands on its own as an effective and engaging high-level adventure. Its strength lies in its atmosphere, its open structure, and its presentation of a society of intelligent monsters bound by codes of strength and tradition. While Steading of the Hill Giant Chief is more immediately accessible and Hall of the Fire Giant King arguably more refined, I think Glacial Rift does something unique in presenting a wilderness-like dungeon. I think it's understandable that it's not often celebrated, but I nevertheless think it would be a mistake to overlook it, as it's a fine example of Gygaxian adventure design that rewards careful and clever play.
