Khallyon is not the only one in being stunned by Krullzure's question, most Contemporary people are in the same circumstance, after all, they learned the basics about the IGNUS in Tiaone, which should apply to the Old Ones too.
"The IGNUS is what motivates us, a fundamental part of ourselves that we mostly ignore due to the development of our lives, as we don't have control over them… , Yet, to know your respective IGNUS, all you need to do is check the Fake Tattoos in the internal part of your forearms".
The Rogue Cadet explanation is initially understood by the Old Ones, until he said the last part of his phrase.
Still without lowering her hand, Krullzure makes a new sign, speaking in a low, trembling voice, to not sound ungrateful or impertinent "W-What F-Fake T-Tattoos?".
{Is she serious?!…}
The facial expression of Khallyon deforms itself to denote how flabbergasted is he, as the Rogue Cadet is unable to focus for a couple of seconds.
