A Blood-Encrusted Letter
Through the filth you can make out a few of the words. It seems this letter was sent by someone named "Gorluxor". He ordered the Dark Artifacts to be delivered to him inside the Temple. It seems that only with their help will he be able to corrupt Tensess' Gift...
This Gorluxor sounds like a very dangerous person. You should probably show this letter to Voisvet Belov.
It's from Gorluxor, that old Xadaganian dog! Damn! Why did he have to be involved with this?
