As Marie-Louise reads through the journal of one Abbalonian Descargo, she finds it lacking in mentions of evil or demons or C'thalet for much of the manuscript. However, about a third of the way through the document, the handwriting changes. What was once a flowing delicate script suddenly took on a different character. The words were largely still in common, with a smattering of Draconic in the margins. But now, there were definite hesitation points where the ink made large splotches, obscuring some of the work. If it weren't for the fact that the tone reads almost exactly the same, you would think it was a different author.
That's when she notices a bit of ink along the binding. She grabs a reflecting mirror and redirects the light from one of the table lamps down onto the page. Etched in tiny lines right where the seam meets is a simple Abyssal invection:
Fhaagathra! Phl'gw'nathi crwlagrah C'thalet Pwgra nghsossotha! [ +- ] Abyssal
Mortal scum! Heed now the words of the immortal C'thalet! Your time has come and you will all perish before the mighty darkness!
The same thing the black hooded man had been yelling in the square.
Deeper in the book, she starts to see small sketches of runes. Some Abyssal in nature, others languages she doesn't know. The bits and pieces she can make out, it seems to be some sort of recipe spread out through journalling entries. On the second to last page is a single entry, dated some fourteen hundred years ago. The following entry is in a mix of abyssal and common. On the last page is a note written in a totally different hand, dated about six hundred years ago. At a glance it appears to be a translation.
Today I set upon my destiny. No more wishing and wanting, the day of realization is here. I am the herald of the chaos to come. Madness is my pawn and the lands shall be my board. I have spent these many months cajoling and pleading with that grandest of demons, that lord of the unruly. His promises of power have been good. I feel the surge of energy deep in my soul, opening my minds. I commit now to the last wish of my great patron, He Who Shall Rule The Kingdoms. C'thalet the Mad King. I finally have the items to summon him and to pledge to him for this taste of power. It shall be glorious. The Mage Lords will rue the day they shunned me. The name Abbalonian Descargo will echo throughout time immemorial!
That is the last writing in the book. You recall from the catalog that there was no Journal 18 listed.
