The story:

Several years have passed since a brave group of adventurers—Severax the Cleric, Gamliel the Paladin, and Selivar the Sorcerer—killed the evil vampire lord Strahd von Zarovich, breaking his curse and returning the sun to the land of Barovia. The party went about their lives, until one fateful day when "a spell gone wrong sent them to the far away land of Equestria.":https://www.fimfiction.net/story/474246/tpk-total-party-katastrophe There, they met Twilight Sparkle and her friends, and helped them defeat the most dire threat they'd ever faced. Afterwards, our heroes bid farewell to their new pony friends, with an invitation for them to come visit some day.

Here, we see the unlikely group of friends meeting at the Blue Water Inn in the town of Vallaki. Severax reluctantly agreed to an arm-wrestling contest with Big Macintosh. Seeing as the humble dragonborn doesn't like flaunting his natural strength, his embarrassment is only matched by Applejack's amusement at her brother's struggle.

Gamliel somehow got himself roped into a drinking contest with Rainbow Dash, and it doesn't look like he's doing too well. Let's hope Lay On Hands also prevents hangovers...

Meanwhile, Selivar regales Twilight and Spike with tales of their adventures and a demonstration of his ice spells. Spike seems in awe of the tale that the Draconic sorcerer is weaving, while Twilight is eagerly devouring knowledge about this new form of magic.
