Stabbed in the Back

We made our way back to the catacombs again with Egert, who was definitely looking the worse for wear. He managed to tell us that the followers of the Blue Flame had attacked the gate that Elodin was watching over, and among their number was Darneska. In the fight that ensued the gate portal was shattered. The blue flames were actually used but the cult followers as a portal themselves, and he said that he, Bevil, and Elodin followed the cult to this dungeon. Darneska was heard to say something about a scroll and that they were in league with a "Dark King". They were in Barad Elion to meet Father Briar. Whatever the Father was studying is apparently coming to life.
Egert tried to explain that the well was an illusion, not a planar portal as I had thought. The date on the note left by Bevil was apparently some sort of code; he clearly overestimated our ability to decipher it. The 15th really meant 1 + 5, which is 6. Egert explained that there were 6 individuals with Darneska. He then began to babble about how Bevil dreams in algoriths, and I couldn't make much sense of it. Probably incoherent from blood loss.
We made a fire and cooked some of the meat of the creatures we killed. Prestidigitation made it somewhat more palpable, but barely. Dru and Zarruk then took first watch.
(Dru fell asleep on watch and dreamed of his sister Dray. She is being held by an unidentified female somewhere other than the material plane.)
I dreamed, finally the many voices were still, and I only heard one, the voice of Silvanus. "Do you see the balance that's been brought?" I saw him in my dream, an old man with a tree guardian. At his side were two others, both Fey'ri. My parents. He said with all sincerity that they had become close friends and that they were safe with him. I was shaken. Beocca had told me none of my race could enter Silvanus's realm in the afterlife, and I even gave up my wings to prove my devotion and willingness to reject my race and heritage. And yet there they were, completely happy with the Great Oak Father. Could Beocca have lied to me? They told me "Until you face the things that have tampered with who you are, your life will spiral out of control." And my mother looked at me and made me promise "No more deals, and find your siblings".
On my watch I take time to go through my ritual prayers, and use the oak leaf that Silvanus gifted me as part of the ritual. It is different than the others, still vibrant with life rather than dry and brittle, almost emitting an aura. Nothing disturbed our rest, and we eventually all awoke and made the best of the left over meat for a hasty breakfast. Going back to the chamber where we found Egert, we head to the two old wooden doors with brass handles. Dru used his magic staff to open the doors safely, and we entered next into a room with large posts, curved walls, and doors to the south. Bones, cloth, and armor littered the floor. There was the smell of a wolf again, and something was causing Mirielle to be unsettled. While trying to decide which way to go, Dru picked up one of the bones on the floor to throw down a tunnel and apparently set off some sort of magic trap, immediately struck with terrible pain in his mind. Perhaps at some point before we leave this dungeon the firbolg with learn not to touch everything he sees. We eventually chose a path to follow, and entered a tunnel full of insect buzzing around and covered in dark slime. We eventually emerged into a room where a table had been set at the far end, and there are three figures gathered around it. One was the wolf-like creature we had encountered the day before, another was Darneska, and the third was Bevil. All were sitting perfectly still. As Dru moved forward, the wolf and Darneska vanished.
Bevil was pale white, eyes black, his face bearing a slight smirk.
Darneska and the wolf attacked us, and while we had a rough time we eventually killed both of them and Darneska's infernal cloak, in large part thanks to Zarruk's magic dagger taking Darneska out for a large part of the fight. After they were killed however, Bevil remained in a trance-like state. I though he was being possessed by some other entity. He finally roused enough to speak to us, and began talking about how the "ritual" was almost complete. He said strange things like "The farmer should have kept you busy longer" and "Barad Ellion will soon be in ruins". As he spoke it became increasingly clear that Bevil was not who we thought he was. He was in fact the god Bane. Darneska had created some sort of void, and not-Bevil kicked the corpses into it where they were completely swallowed up.
Dru wanted to take the fight to him right then, but I tried to talk him down. I had barely survived the fight with Darneska, and was no where near ready to fight a god yet. Dru pressed the issue though, so Bane decided to make a show of strength and telepathically ripped Dru's magic staff from his hands, crushing it into a black void. We eventually struck a deal with Bane that we would both go our separate ways for now, and he disappeared from sight. Egert did not take the revelation well, and all of us were shaken. If Bevil was actually an evil god this whole time, and Sibil is in the hands of Lilith, the Splinters seem to be done.
