There are two people that know 100% of that story. You're not Twist, you're not me, so you are just making shit up.

The full story is this:
Night A, like midnight EST: Light is in full tilt, no evils on to get back items. Fort is going for Tiamat, I and a few other Nexus people join them. I volunteered Nexus to go because my belief was the three Nexus could do nothing to the horde of fort people online, so we needed to encourage them to die somehow. I believed it would be a suicide mission as Tiamat had never been killed. I think there are like ten of us in total. All of us died. There are reasons this was a good plan from my end and a bad one from theirs.

Night B: A week or two later. Light in full sway. Fort is going for Tiamat again, in a smaller group. I forbid the other Nexus people from joining this time, but I go with them as I think I offered to join and I did not want them not to make the attempt. However, turns out they are going to the Blue lair first, then to Tiamat, so I go to the Blue Lair with them. Twist speaks to me on CB, I essentially tell him my plan was to ensure we all die fighting Tiamat. Twist watches as we kill the ancient Blue, and he comes vis in the lair, uninducts me on the spot, and rightfully so.

You know what happened then? We went and killed Tiamat, and Twist rewarded all involved with Imm XP, the dragonslayer edge and a title, including Allysia.
So yeah, Twist did nothing to block the attempt. What he did was punish a Nexus leader for aiding the light when light was in full tilt. RP dictated he boot me since Twist was a NEXUS IMM. I admitted my plan failed and accepted the punishment. Name one thing Twist did wrong in any of this. If we all had died, we would have probably applauded me. It was a gamble, and I lost.

Did I break RP in making the attempt? Not at all, Allysia was all about finding any available means to the end. I knew well what the consequences would be for my actions if the fort people lived. I could have nofollowed and fiended right after the Blue, but Allysia would never betray people, so she bore the brunt for the failure. After Tiamat I probably could have done the same thing even as an outcast, but really at that point Allysia was outside of Nexus and not bound to it anymore. So if the plan If Twist did not boot me, everyone would have bitched at him for not booting me.

Rayihn allows me to rejoin later on.
End of story.
