I hope the title isn't so ambiguous such that it doesn't actually resemble what I'm asking, but I'm trying to keep the title spoiler free.
So, in the Tomb of Annihilation adventure for D&D 5e, there is a location in Chult called Dungrunglung (pp. 49-52). This location includes a maze.
When you first arrive, the party is greeted by some grungs, who live here in Dungrunglung. Depending on the party's apparent strength, they are either polite or less polite, but either way they want you to go to the centre of Dungrunglung (which means going through the maze) to meet their king. At least in the former case (weak looking party), it describes, on page 49 (italic emphasis mine):
... 1d6 + 6 grungs with green skin (warriors) surround them as soon as they enter the thorn maze, and press them to attend an audience with the king. The grungs attack and subdue characters who resist. If the adventurers accept, they are taken through the maze to the shrine, where they are received by King Groak.So, the moment the party step into the maze (which surrounds the grung settlement of Dungrunglung), the grungs "greet" them immediately and escort them to the centre, which of course means they are going through the maze with the party. On page 49, it has this to say about the maze itself, and what one may expect whilst trying to navigate it:
The maze's passages are open to the sky and magically change configuration every minute or so, turning passageways into dead ends, and vice versa. Whichever character is leading the way through the maze must make six successful DC 15 Wisdom (Survival) checks to find the entrance to the settlement (area 2). Each successful or failed check represents 1 minute of searching the maze.This, to me, implies that the grungs themselves can get lost in their own maze (and after apparently having just travelled through it already to greet the party). Is this true?
Is there anything that I've missed that might imply that, while being guided through the maze by the grungs, the (escorted) party and grungs do not get lost? Or do the party or the grungs still need to make Survival checks, potentially getting lost?
