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.
"Doesn't wanna talk," she murmurs. "Buffs and then I'll try to faerie fire them for you, wizard in blue, guards in purple if they're close enough by then. Fox's Cunning," for Garrus, "Haste," for everybody, "Faerie Fire."
The wizard lights up for a second, then flickers out. The guards light up and stay lit up.
Garrus shoots two of them; they drop, jittering with electrical energy.
Jojo speeds towards the pool. The guards try to shoot him, but he's juking in such a way that they can't get a proper bead on him.
He reaches the pool of darkness and somehow causes his body to start glowing, lighting up his surroundings like a torch. He starts beating up the wizard, who doesn't seem to have prepared for someone to be up in his business six seconds after having been a hundred feet away.
Belmarniss casts herself a mage armor from the staff and gets as close as she must to hit the wizard with an admonishing ray.
The wizard drops like a rock.
Deekin shoots one of the guards with a bolt from his crossbow, humming his fight song.
And Garrus drops the remaining guards.
"Well, that wasn't so bad," he comments. "And if that wizard's still alive, we might be able to get some information out of him."
Garrus! Garrus has the rope. He ties up the wizard, then has Deekin cast a Cure Light Wounds to get him back to consciousness.
The wizard licks his lips nervously when he observes his circumstances. "How embarrassing," he says.
"I'm from another planet, you know fuckall about my family situation. Folks, what do we want to know?"
"Where be Halaster? And why drow be attacking Waterdeep? And who be Valsharess?"
"I have no idea where Halaster is besides 'deeper in Undermountain,' I was assigned to guard a door. The Valsharess intends to conquer your pathetic city, and from there the entire surface world. She was Matron Mother of House Kilath, and she is now Empress of all drow."
"Wow, Empress of all drow, what a blowhard. And how do you feel about this assignment in light of the current situation?"
"While I recognize that it is pointless to complain of not having been defeated legitimately," the man sniffs, "a party without your particular advantages would likely have been stymied by my arcane powers. Your mouse engaged me in melee combat before I could cast even a single spell, and as I'm sure you know a single spell can be the difference between life and death."
The spell fizzles. The caster has some very inventive things to say about this in Undercommon.
"Deekin think that be very impolite way of saying no," Deekin comments.
Jojo sighs. "My vows do still allow me to execute a prisoner who has demonstrated that we are unable to effectively contain him, Garrus."
That said, he reaches down and snaps the wizard's neck.
And Deekin goes through his stuff. "Hmm, ring... Commander's Ring, good if locked chests in future. Headband... ooh, Vast Intelligence, Belmarniss want? And..."
He extracts three lengths of chain from the wizard's pocket. One is green, one is yellow, one is blue. "Collected puzzle pieces for door! Very polite."
Deekin goes around attaching chains to appropriately colored pedestals, then stops. "Four pedestals, three chains... dang it. Wizard not have all puzzle pieces."
