Returning to the distillery proves a waste of time for Errol. Apart from the still there is pile of fire wood and a rack filled with bottled brandy that is probably more use stripping tar than drinking, only the most desperate drunk would drink this stuff.
Moving on to the scriptorium proves more fruitful. Despite the poor light you quickly work out that many of the texts are worthless, mostly accounting from many many years ago, then just as you are about to give up you find a sheaf labeled Marlos's Testament. The parchment is much newer and there are many copies of the same texts. The opening is the dull, sorrowful whining of a self obsessed sadist, but skipping ahead, you read a passage that seams to describe his arrival at this monastery.
Marlos styles himself as The Prophet of Earth and was lead to something called the Fane of the Eye where he was gifted a powerful weapon. After that he returned to the monastery where meditation and visions led him to write his testament while he awaited other followers of Ogremoch . As his followers grew, he was able to move below ground into an ancient dwarven stronghold and establish a Temple to Ogremoch, leaving Hellenrae to oversee the monastery. The testament ends abruptly, explaining how Marlos is nurturing something he calls the Black Geode and expects the Evergrowing Mountain" to come and remake these lands in its own image.
