[Twine 2.1.1][SugarCube 2.14] Traversing to a passage when a condition is met

Hey there!

I'm in the process of creating a way to automatically travel to a location without entering an infinite loop. Now, I've seen two methods of doing this. There's a topic about this, but I can't seem to find it (not even with google, the title must've been confusing). That concept showed using 'PassageHeader' (?, probably not, no idea...) and a boolean to send the player to somewhere else when an event is triggered.

I also remember TME posted a code, which enables one to override the next passage when a certain time has passed in game (event occurs):
This can be found here:

Does anyone know more methods of doing this?
Say, I have multiple quests going and I want to go to a passage when a quest is complete (an enemy is slain, a sword was picked up, you lost all your health and died, etc.). How do I manage these without conflicting?

I setup a quest system the following way:

<<set $equipEnchantedSilverSwordQuest =
{
	item: { name:"Enchanted Silver Sword", id: "enchanted.silver.sword" },
	character: $player
}>>
<<set $slayingCoboldSkeletonQuest =
{
	numEnemies: 8,
	enemyTypes: ["Cobold", "Skeleton"]
}>>
<<set $beThereOnTimeQuest =
{
        date: "20.12.428",
        time: "22:00"
}>>
<<set $silversword_log = 
{
	name: "Silver Sword Equip Quest Name",
	startPassage: "Quest - Equip Your Enchanted Silver Sword",
	onSuccess: {passage: "Battlegrounds", message: "Now go and slay some cobolds and skeletons"},
	questType: $equipEnchantedSilverSwordQuest,
	description: "This is a description for Quest - Equip Your Enchanted Silver Sword"
}>>
<<set $quest1_log =
{
	name: "Quest 1 Name",
	startPassage: "Quest 1 - Your Castle",
	onSuccess: {passage: "Party House", message: "congratulations for completing quest 1"},
	questType: $slayingCoboldSkeletonQuest,
	description: "This is a description for Quest 1"
}>>
<<set $returnBeforeNightfall
{
        name: "Quest - Return before nightfall",
	startPassage: "Quest 1 - Your Castle",
	onSuccess: {passage: "Couch - Resting", message: "You return your castle to rest until the morning."},
        onFailure:  {passage: "Graveyard - Game Over", message: "You've failed to return to your sanctuary before nightfall, your reward is death by cobolts and skeletons!"},
	questType: $beThereOnTimeQuest ,
	description: "This is a description for Quest - Return before nightfall"
}>>

// now of course you'd put these into an array and loop through them 

My question is, which special passage or Task Object would you use and how?
