Fear of the Deep
The images stopped along with the accompanying noise.
Hao Xuan opened his eyes and looked towards the white ant, somewhat at a loss for words.
He didn't know what method the Queen used to send him those images, but somehow he could tell they weren't fabricated.
There was no reasonable explanation why he thought so, but he knew deep inside that that was what actually happened.
And what they implied was a very simple thing. Every time he called someone in or out of the Mind Palace, those invisible runes played some sort of a part in them. And doing it too often could 'overheat' or overload them in a sense and he wouldn't be able to do so again for a little while afterwards.
It had nothing to do with the Queen or anyone else for that matter, but was related to his Soul Severing Constitution instead.
