I'm preparing to run my first Dungeon World one-shot tomorrow using the Kickstarter module Within the Devil's Reach, and I'm wondering about the encounters it lists. Are they meant to be scaled to the party in any way or presented as written? For example - and spoiler alert for The Silent Tomb Speaks - is the "stat block" for the wolves meant to represent a small pack thrown against the party, or are those stats for a single wolf and it's up to the GM to decide how many to employ?

If it's the latter, any advice for a new GM on how to scale a Dungeon World encounter?
