The culmination of my oneshot with just two of my players because the other two are out of country. One was an elephant-man paladin and the other was a minotaur fighter (both lvl 10) named Tim and Tested respectively. They were both toll collectors, with Tim having spent 45 years collecting tolls on the bridge. One day an army of elves, orcs, hobbits, humans and dwarves passed by, led by a huge Knight. Tim and Tested insisted on payment and the Knight, Sir Regi Reinauld (whom they dubbed Jesus) acquiesced, offering them an ornate necklace and five gold to cover the cost of letting his army pass. They took the five gold but declined the necklace, privately musing that it was nice of Sir Regi to not try to take the bridge by force.
Sir Regi offered to help defend but Tested had a death wish and Tim was prepared to go down with the bridge, so they wished Sir Regi a glorious death and bid him adieu. Tim proceeded to prepare some tea and set the bridge up for incineration, whilst Tim was gone an assassin continuously tried to assassinate Tested but was incapable of damaging him or inflicting his poison upon him. By the time Tim came back, Tested was cushioned with crossbow bolts but completely unharmed.
Eventually the vanguard arrives, led by a husk (bodak stats but more sun resistant in exchange for not having instant necro damage hit), the assassin and a unit of musketmen. Tim bravely faces the husk and musketmen alone whilst Tested wakes up to the sound of gunfire after sleeping in the nearby forest. The assassin tries to backstab Tested but is completely unable to break through his armour, leading to the assassin being pummeled to inches of his life. Whilst Tested negotiates with the assassin (named Cho) and manages to convince him to join the toll collector squad, Tim is fighting for his dear life, getting the life succ'd out of him by the husk whilst the musketmen fire devastating volleys. Tim manages to call upon angels to smite the husk in a brutal duel, but despite going prone into half cover still manages to fail a dex saving throw with advantage and takes another devastating volley full on.
At this point Tim is on death's door and Tested goes to go kill the musketmen. By the time Tested finishes slaughtering the musketmen, who despite all of Tested's efforts to make them break and flee held their ground bravely to the last man, Tim had two successful death saves and two failures. Tested makes it to Tim to try and stabilise him, but between him and Cho, neither of them understands medicine. Tim just barely passes his last death save, waking up with 1 HP.
Cue some of the best RP I'd ever seen, with the two of them just arguing over whether to destroy the bridge or not. Tim would rather die with the bridge which had been his whole life purpose, whilst Tested shocked him with emotional pleads and insults, breaking Tim out of his mid-life crisis. They burn the bridge and in the next four hours a squadron of skeletons arrive. They take turns taking potshots at the skeletons but don't know how to use guns, damaging a few bones but killing none of them. As the hours go by hundreds of thousands of skeletons amass on the river but stop at the burnt bridge. Eventually a husk arrives and they taunt the husk, ignoring its wicked tricks, and set off to go find Jesus and his caravan of troops - with the end goal of finding a ferry and making it to drift city.
There was also a long running joke that everyone was shocked the toll collectors had no idea there was a civil war going on, and Tim and Tested both defended themselves by saying they hadn't left the toll bridge in decades and months respectively.
