To be fair, Ames was not as invested in Array as most of her kin. It was not that she found it too complicated or dull; instead, because it was a magic branch that her husband, Zane, excelled in, she decided to focus on excelling in another branch.
In any case, her father's proficiency in Array was also good, and there was also Ducal. So Ames never really thought much about it.
Consequently, she never gave much consideration to Kyran's communication device. It wasn't that she lacked trust in his creation; instead, like many with only a fundamental understanding of Array, when someone claimed that an array formation in some location was beyond comprehension for anyone in this era, she took their word for it without question.
That was why Ames never tried accessing the communication device Kyran gave her.
