These Runes were all part of the basic Runes and they were the Rune of disguise, the Rune of language, the Rune of limitation and the Rune of revelation.

Roman then said to him, 'Okay, let's try it this way and let me know if you want me to release the energy of more than one high grade Talisman at a time.'
