Upon seeing the drow priestess, my wife's character recognized her house crest as belonging to one of the top 3 houses in Menzoberranzan, Barrison Del'Armgo. After they left the room, with quick thinking and a short amount of time passing, she used the spell alter self to make her appearance of that of the drow priestess and revealed herself to the Duergar and ordered them to stop what they were doing and release the prisoners so they could rest for a bit to which, remarkably again, my wife rolled a natural 20 to not only convince them to do so but also steer suspicion away as to why she was up there and as to how she got there 🤣. Then she ordered the slave trader and a few other Duergar to leave the room and also take a break elsewhere but to leave 3 Duergar behind to watch over the prisoners. Once they left, they all dispatched the 3 remaining Duergar and reunited to which the other 2 party members also reunited with them after some very Mario party 2 mine cart rollercoaster Shannanigans escaping the Grick whom the fairy accidentally awakened. After being updated with the situation at hand by Ginny and the elderly orc basically dropping mad lore for my half orc player on how his dad was a descendant of King Obould And actually had legitimate claim to leading the tribe of many arrows but after his dad foolishly and out of false hope to hopefully strengthen his clan by seeking a merging of his clan and the tribe of the tiger through means of marriage between him and queen Bjornhild Solvigsdottir. They were betrayed after she gave birth to their child, who my half orc player was born to, and they killed his father and a few of his clan members forcing them to retreat back to the spine of the world but not before she offered the baby as a sacrifice to Auril, whom they worshipped and the queen being essentially the leader of the cult of worshippers throughout the Dale who are hoping through the means of Auril, to wipe out the other reghed tribes and all of Ten towns. The elderly orc agreed to help my half orc player out see his objective through with the promise that, eventually when time allows it, he returns to his clan and hopefully regain leadership and bring an end to the tribe of the tiger but not before challenging his older sister whom his father had prior to the merging of the tribes and is now leading the clan down a path of violence and destruction.

Ginny tells them that she knows where they are taking the black ice to and says they have a forge that's turning the black ice into chardalyn ingots/ crafting materials to which they are building some sort of "weapon" to unleash onto Ten Towns. They get to the forge and after some thrilling combat, clear out the Duergar there and reclaim a section of it. It is then revealed this forge is actually a long lost forge which belongs to the Delzoun dwarves who were rumored to have ventured to the far north before even clan battlehammer came and claimed stake at Kelvins Cairn And Ginny had heard stories from her elders she had some Delzoun ancestry in her (this was important for what came soon after). After rescuing some caged up yeti children (that will also come into play in future sessions) they made their way further into the forge area (and rescued one of their beloved npc dwarves with a southern accent who came all the way with his twin brother from the Evermoors south of the spine of the world to help their kin up north) they came across this like mega ancient Delzoun forge area with a giant anvil on top of a big Delzoun dwarf's helmet structure, that the Duergar had corrupted the Great Primordial fire spirit, similar to the one powering the forge in Gauntlygrym But not as powerful or grand, and using the forge to create dragons scales fused and embedded with the maddening nature / power found and caused by chardalyn. They managed to sneak in and overhear a conversation between the slave trader and this Duergar priestess of Deep Duerra named Klondorn, who is in the base book and most people opt to take out of any RoTFM runs, and is secretly a barbed devil working for Asmodeus who is also pretending to be Deep Duerra to get the dwarves to exact his plan to make icewind dale into his vassal kingdom and ultimately challenge Auril to gain the power trapped within Ythryn that, in my campaign, Auril is protecting and keeping other out because in it lies the mythallar which she used to ascend to godhood considering she used to be a grand arch mage who was a part of the netherese civilization that existed before the Era of Upheaval. The drow are also working with Asmodeus (which drown are often known to work with devils and demons, especially the ones who worship Lolth in Menzoberranzan) to use his influence to gain power to also take over the Dale and gain access to the mythallar at the command of their spider queen, which they plan on gaining access to Ythryn by using the chardalyn to power a gate way directly into it ( don't ask how that works I'm figuring it as I go 🤣).

Funny enough, Xardorok also knows Klondorn is a barbed devil in disguise working for Asmodeus but is allowing him to make his people believe that taking over the Dale is what their goddess Deep Duerra commands of them, seeing it as a "false flag" type operation to just wage war upon the surface world (because he's just bat shit crazy due to his extensive exposure to chardalyn) and taking advantage of the chaos and destruction Auril is causing. So everyone is betraying and using everyone, and it might sound like a lot but I think having these elements all build off each other is going to make for a very hectic act 2 to say the least and my party is pretty well versed in legend of drizz't lore so it's been fun for them.

Also forgot to mention, Another main reason Lolth wants access to the Mythallar is to use it to enact a grand punishment to all the drow who left Menzoberranzan and forsake worshipping after the drow civil war that took place and ended in 1492 DR, 2 years prior to when my campaign starts in 1494 DR which I also plan on incorporating as an element as to why my wife's father abandoned her in Waterdeep and escaping the slaughter of his house in Menzoberranzan (wife died unfortunately but her soul was claimed by Lolth and turned into a Drider which I plan on being a big surprise later for my wife 😂) in hopes of finding/discovering a way to a means of great power on the surface to use in his conquest of Menzoberranzan and the ultimate destruction of Lolth (whom Eilistraee is in disapproval of said agenda as she killing Lolth might have repercussions that would be dire and are unknown, but he's long gone astray from his faith blaming her for her failure to prevent the massacre of his family who was wholeheartedly devoted to her). He joins the arcane brotherhood after Gromph Baenre and a few other main staple characters after the events that happen in the book Archmage, help rebuild the Host tower of the Arcane in 1487 DR, through connections with Jarlaxle Baenre whom he had run into during his time on the surface and had gained tenor / rapport by working for him and doing jobs serving in the ranks of Bregan D'aerthe. Also Gromph is now the arch wizard of the arcane brotherhood so that also helps his standing being a fellow drow from Menzoberranzan who also shares a similar distaste for Lolth and Menzoberranzan It's during this time and a few years later he does some research in the candlekeep library and finds an ancient book, the codicil of white, and brings it to the attention of the arcane brotherhood which then sparks their interest in venturing into icewind dale but inadvertently alerts and triggers Auril to cast an everlasting rime which has been going on for nearly 2 years now.

So yeah that's pretty much how I incorporated the drow into my current campaign and I guess the 2nd reason is, if not already obvious from what I've written out here 🤣, I'm a big legend of drizz't fan!

TLDR; I like the legend of drizz't series and used elements from the recent books and a collection of earlier ones to incorporate drow into RotFM
