'Of course, lady.'
The baron offers the rest of the mages one last beady look before he escorts Illshana up the stairs and to a larger room, and offers a room where a number of other women are sleeping before bowing and walking to his room. 'Lady, while I cannot sleep, I wish you the best in your endeavors. May God protect you.'
Not ten minutes later the group are assembled, reading in hand.
Assuming someone reads the notes left on the desk in the room with the creature in the circle, you find out some interesting information. The notes appear to be the helter-skelter remains of a diary, a member who does not refer to him or herself, but signs with the symbol of a linked chain. The writing is in Latin.
'...that fool Flambeau! He has claimed to be able to master Hell itself. I fear for my life and the lives of my Sodales; the Order be damned, we'll be dead before they can March us. I fear that standard Magical theory has proven all too true; my Intellego magics cannot divine anything other than lies..'
'...Idiocy upon idiocy. Again the fool has poured misery upon us; curse the charter from forbidding us to kill him! And alas, he could kill us all if he wished, and easily, charter or otherwise. I fear that Leo of Verditius will die to his hand if he keeps speaking out against him. I also fear that already that fool has lost his soul. Is it a demon speaking from within him? I must come up with a plan.'
'... I must act, I know it. Leo has died, his protections rendered useless when our cursed leader entered his room and slew him. I can hear him muttering to himself again. I must away to the forest; I must use the only power I know will act on this, the Lady of Merciful Sorrows. If I capture her daughter, I can bargain. I know the child can heal itself; it will have to be something that I do not overly enrage the Lady, some kind of token that I mean business. I hate to molest my brethren so, but a fate far worse than an angered fey awaits me unless I get the Lady to act.'
You find the fate of the covenant in the scattered diary. A mage fell into infernalism, causing the original claims against the covenant. His sodales attempted to divert the disaster, but it was too late. Possessed by the demon, the head of the covenant fell into murderous and bloody rampages, and his Sodales were powerless to stop the battle-mage, and so called upon a power they had little experience with to gain what they needed to undo the curse. Understanding bargains, they captured the daughter of the Lady. After this, you don't know what happened; the diary ends with a description of the magic used to bind the creature; in fact, it is a highly powerful ward, designed to keep the creature in - a fey creature.
