Things in Venetia had gone from bad to worse. The heroes’ armies were beginning to run low on supplies. Morale was virtually extinguished; with the Thacien soldiers believing their cause lost with the city of Scion, and the men of the Army of Bahamut wanting nothing more than to leave the desert behind and press on toward Cavalonia. Meanwhile, the Gnolls had acquired a fleet and cut off the supply lines to Corinth; and they had several portals to the Abyss active in Scion and the Northern Kingdoms, and they were bringing in reinforcements constantly. Additionally, they had lost contact with their Yuan-Ti allies, if any of them even remained.
After some deliberation, the party elected to return to Sigil with the remaining Venetians and the Army of Bahamut.
Thus they did so, abandoning the ancient castle of Thacien Keep and flooding the Lowtown of Sigil with refugees. Much to the ire of the Lady of Pain, who demanded that they leave immediately.
The party went to speak with the leaders of Thacien and the Ring of Commanders. The Venetians agreed to travel to Llanowar, which was beset by hordes of orcs descending out of the Wilds. The Ring of Commanders however, refused. They didn’t want the Army of Bahamut to become bogged down fighting another hopeless war so far from their ultimate goal: Cavalonia.
But the party didn’t have time to waste deliberating with the Ring of Commanders. They needed to get back to Venetia to slay Yeenoghu. They knew he was holed up in the remains of the Tower of Scion. They negotiated with the Lady of Pain for the key that would unlock the door to his throne room, and in exchange promised that the refugees would be on their way.
The party then traveled to Scion. They planned to summon Nefermandias as they infiltrated the tower, so that the Gnollic horde inhabiting the city would be preoccupied while they battle Yeenoghu. Unfortunately, they forgot to summon Nefermandias until halfway through the battle, though he did eventually fall upon the city.
The door they left through in Sigil happened to belong to a city native, who unfortunately followed them through and into the new palace of the Prince of Gnolls.
After an intense battle, the heroes finally slew Yeenoghu, and then nearly lost a number of their own to Nefermandias. Instead of sticking around to fight the dragon or the remaining Gnolls, they collected their own and beat a hasty retreat to Sigil.
There arrived to find the city embroiled in conflict. The Sons of Mercy and the Army of Bahamut had gone to war. Apparently, the Lady of Pain had attempted to kill Dante and Davros (and in the process actually succeeded in killing a number of skilled warriors) after a rise in tensions caused by the continuing presence of the Army of Bahamut.
The heroes made their way to Dante and Davros (tricking a group of the Sons of Mercy in the process) and learned that the Army of Bahamut was hard-pressed. As such, they concocted a plan to infiltrate the palace of the Lady of Pain, and steal the Ring of Keys that allowed teleportation to any realm. They snuck in, disguised as supplies brought by one of Kheldor’s front companies, and gained access to the servants’ passages. Though the guards that they left with the wagons they had brought in ran into some trouble in attempting to keep the Sons of Mercy from finding out what they were up to (only the quick-witted smooth talking of one of the guardsmen kept them from being found out).
The heroes emerged into the Lady of Pain’s throne room. While Kheldor attempted to distract her by offering terms of negotiation the others dispatched the Sons of Mercy who were posted as guards, and Oris made a dash to steal the keys.
In the end it was Kat who, while invisible, took the keys. The party then escaped by using their old Key to the Shadowfell. Somehow however, Oris missed the door and wound up trapped in the palace. He then escaped the way he had come in, taking Kheldor’s guardsmen with him. They retreated to Kheldor’s mansion, and were forced to use the escape exit when the manse was besieged by the Sons of Mercy, taking Kheldor’s butler with them. The mansion was burned to the ground and Kheldor lost all standing with the Lady of Pain. Yet Oris and the other three returned to the Army of Bahamut.
Meanwhile, the others spent some time plane-hopping, trying to figure out the keys that they had, where they led, and which one would lead them back to the Army of Bahamut.
They finally returned to Dante, and surrendered the keys to the Army of Bahamut, who used them to open a door to the realm of Bahamut and bring in reinforcements. Hopefully turning the tide of the battle for Sigil.
