It will not only be the second CHL Final to feature two teams from Sweden - after the inaugural Final in the 2014/15 season - but it will feature the same two teams, after Lulea beat Frolunda 4-2 to lift what is their only title to date.
Frolunda were in the strongest position to reach the Final come tonight's face-offs, thanks to a 2-0 win on the road in the first leg.
But all that hard work seemed to be unravelling early on at home, when Lars Johansson was called for tripping and Johannes Kinvall punished him with a powerplay goal to put Brynas in front on the night after three-and-a-half minutes, following a delightful Kieffer Bellows assist.
With eight minutes to play in the first period, Frolunda clicked into gear and drew level when Theodor Niederbach did well to maintain possession behind the net and tee up Isac Heens who controlled and finished neatly.
However, in the final minute of the first, Bellows was at it again, sending a speculative effort from range on target - Lars Johansson in the Frolunda goal made the save, but could not prevent Johan Larsson from tucking home the rebound to give Brynas a 2-1 lead after 20 minutes.
A missed penalty from Filip Cederqvist midway through the middle period only added to the home side's nerves, but not to Heens', as the coolest man in the Scandinavium followed up to score his second of the game, after Linus Weissbach's initial effort was saved.
That left Brynas needing two unanswered goals in the final 20 minutes to force overtime, and they were given the ideal early chance when Linus Hogberg was called for interference, but they could not capitalise on the powerplay.
That would be the only real chance Brynas would get in the final period, in which no further goals arrived despite eight shots on goal each, meaning it finished 2-2 on the night and 4-2 to Frolunda on aggregate.
The record four-time winners of the CHL are back in the Final since their most-recent triumph in 2020, while Brynas can take some comfort from a Semi-final exit marking their best ever season in European hockey.
Joining them in the all-Swedish Final will be Lulea, who cruised into the showpiece with a 3-2 home win over Swiss side EV Zug, which made for a 6-4 aggregate success.
Lulea had already done the hard part by winning 3-2 away in Switzerland a week ago, and they wasted little time in extending the aggregate advantage, taking the lead in the seventh minute when Brendan Shinnimin shimmied past his marker, and his strike was deflected in by Isac Hedqvist.
Tomas Tatar had been called for hooking with the match still goalless, but he failed to get a handle on his discipline in the 13th minute when he was sent to the box again for high-sticking. Lulea punished him soon after, as Anton Levtchi set up Pontus Andreasson to power the puck into the top corner.
Six minutes into period two, Lulea went 3-0 up on the night when Shinnimin was in the right place to tuck home Oskar Engsund's centre, putting the SHL champions on the brink of a first CHL Final since 2023.
But having been the villain in the first period, Tatar then spearheaded the beginnings of an unlikely Zug comeback - first, he played a neat one-two with Gregory Hofmann, who scored after winning the puck in the Lulea zone.
Then, Tatar burst through the middle to collect Dominik Kubalik's pass from the right and squeezed the puck past Joel Lassinantti to make it 3-2 on the night and 6-4 on aggregate. As with Brynas in the other tie, that left Zug needing two goals without reply in the third period.
Unlike Brynas, Zug dominated the final 20 minutes, outshooting Lulea by 11 shots on goal to two, yet despite conceding a pair of powerplays, the home defence stood firm to secure their second 3-2 win over Zug in these Semi-finals.
It will be Lulea's third appearance in the CHL showpiece in total, after their 2015 victory and their loss to Tappara in 2023. The match is scheduled to be played in Gothenburg on 3rd March.
