To my favorite Docent
I must offer my apologies for not being present upon your return to the Rathir chapterhouse. Continued ponderings regarding the intricasies of the magics involved in the Sun Stone artifact you recovered have compelled me to attempt an experiment of sorts.
Should you receive this missive in time, please consider yourself welcome to join me. I will be found atop the spire of Creathnach Thintri -- Skycrown mountain, as it is called. It shouldn't be difficult to find, as it is the only mountain in all of Erathell.
