Belmarniss can now sorta muddle along in the local common thanks to aggressive use of comprehend languages to hand-translate books after roping a local into teaching her the alphabet. Also she hates teleport traps with every fiber of her being. Also she has figured out at this point that she somehow leveled in sorcerer instead of wizard during the business with the pirates and has no idea why that happened or whether it will happen again. And she has sold this stupid arrowhead to two different curio shops and given up as it seems to be cursed. And she just needs to keep doing what she does, she guesses, till she can teleport herself home. The Yawning Portal is a nicely ironic name.
"Delightful. Where's your desk? Oh, also, what do you eat down here? Haven't passed any mushroom farms."
"My desk is in my office, the door to which I came through in my attempt to crush you. The monsters of Undermountain are actually sustained by Halaster's magic, and fortunately, like the teleportation ward, it's one of the spells that didn't vanish when he did, otherwise we'd be in quite a pickle and would likely have resorted to cannibalism by now. Not that we are not occasionally anthropophagic, but I wouldn't want to live off my subordinates."
"Yeah, that's not sustainable." She pops out from behind the table, doesn't turn her back on the boss, and heads for the desk.
"At the end," Garrus says firmly. "With the exception of immediately useful magic items. If we don't trust one person to carry the loot, something's wrong."
"Magic items are so dang cheap on this planet," she mutters, dumping the loot into the bag of holding.
Deekin shakes the bag a couple of times, then closes it up and shoulders it again. "Deekin find bag in ruins of Undrentide. Deekin find like six bags of holding in ruins of Undrentide actually, but most of them go to Boss and Boss die in big mythallar explosion so Deekin not have them anymore."
"Very shiny very magic crystals, held up lost flying cities of Netheril including Undrentide, all destroyed except one, that one destroyed later. Explode very impressively. Detailed in book."
Deekin grins toothily. "Huzzah!"
They leave the ogre mage whose name they never got, and head back toward the central chamber.
Before they get there, of course, they reach the Hall of Mirrors again.
"So, we know there's probably a rod in there now - do we go in?"
"We don't know that we don't. The ogre said there were five, and there were four levers; on the other hand we have no information on the location of any other rods and so it might be a good idea for us to go for the one we're pretty sure is there, in case one of them is behind a particularly cunning secret door or its owner dropped it down a hole or something."
"That sounds prudent," Jojo nods. "We have precious little information on this puzzle thus far."
"Alright, alright. I'm just trying to be efficient, here."
They continue on, and reach the central chamber in good time. There it stands, just as they remember it, with the bridge blocked by a sequence of colorful pillars, and four levers with rod-shaped slots. The pillars are in the following sequence:
R G B
W B G
Y R W
G Y R
"We have... a white rod and a blue rod, which probably matters. Every straight path forward would require at least two other colors. Also nothing in the front row is either. We might need four? I don't see us needing five, there's only four slots."
"Sounds about right. Well, we can head south and see if the other two drop into our laps; shall we? Or shall we rest, actually, I know I talked a big game about taking that ogre down without a sweat but his minions were kind of exhausting."
