You know. I'm glad you mentioned Volcanalis. There's an upcoming film Pompeii scheduled to launch late this month. Wonder how those people scream "VOLCANALIS!!!" Renard's decryption-readings of the Volcanalis part in Grimmopedia gave Nick's book reading quite a different atmosphere.
Also, it is now seemed interesting that Sean Renard is the one decrypting the Grimm Diary issue Volcanalis. Sasha Roiz also stars in the very soon upcoming film Pompeii. He gonna scream out loud, "VOL! CAN! A! LIS!!!"?
