Recap
"Vox Machina, this intrepid band of adventurers, misfits, whatever you must call them, completed an adventure through the Underdark, a very dangerous, cavernous [place]. After completing this Underdark challenge, they discovered and managed to extract an evil artifact known as the Horn of Orcus that held great, great power and seemingly has a partner somewhere in the world that's unknown, but the one they've acquired is indestructible as far as folks know, and it was decided by the Council of Tal'Dorei and Vox Machina that it should be sealed away, hopefully forgotten for the rest of eternity. The best place to do so came up in the conversation to be in the city of Vasselheim—which is on a different continent far to the northwest of Tal'Dorei, the kingdom in which most of the story to this point has taken place—to be sealed in what is referred to as the Platinum Sanctuary, the oldest existing temple to Bahamut, the good platinum dragon deity.

"So they were given passage on a skyship to cross the Ozmit Sea to Othanzia, the continent that houses the capital city Vasselheim. The group gathered together, rode onto a magically elevated skyship, and traversing the ocean, carrying the Horn of Orcus within this holy container. They found themselves, over the ocean, suddenly attacked by a band of what seemed to be wyvern- and griffon-riding bandits. A battle took place on the top of this skyship, some of the magic being taken out, a few lives lost, but the party managed to persevere, taking a captive, and continuing on their journey, the Horn of Orcus and its container kept safe."

Part I
As Vox Machina completes the journey across the Ozmit Sea, Tiberius and Scanlan engage in a strange math workshop until Lady Kima arrives and prepares the group for the culture shock awaiting them in Othanzia's capital city of Vasselheim. The airship touches down, and a representative from the Platinum Sanctuary escorts them and the payload, through the chilled streets to the head of their order—Highbearer Vord himself.

The task is laid before them: enter the Hall of the Exalt, an ancient vault below the Platinum Sanctuary; exterminate the invading vermin; seal away the reliquary containing the dreaded Horn of Orcus; and return safely. Easier said than done, as some of the Hall's defenses are active and the party is forced to traverse a number of deadly traps in hopes of being rid of the evil artifact once and for all.

Part II
The party successfully places the Horn of Orcus in the vault, and everyone quickly exits as two platinum golems appear to defend it. Upon returning to the Platinum Sanctuary, Highbearer Vord mentions a recently uncovered temple to Sarenrae in the city, long forgotten and in disrepair. Pike feels that she must stay to help restore the temple, and says a tearful farewell to the rest of Vox Machina, promising to return to them when she can.
