[ A spiritual plane, where something that Thancred can only perceive as being like creation magicks was possible? The closest approximation he can think of is the aetherial sea, a place that exists somewhere between life and death, though this does not seem to involve the same risks as making use of the Aitiascope.

More interesting still is that the people native to this place are not aware of the Summoned's ability to access this "Horizon." That is reason alone for him to wish to explore it, as Ambrose and the other mages here already know more about him than he'd like. It would help him sleep better if he could hold something over them, as well. ]

I have plenty of experience in being discreet, you need not worry there. [ Yet he nods his head in quiet thanks that Stephen was willing to share this sensitive information with him. He does have some concerns that he'll struggle to access this plane given the scars that Lahabrea and Y'shtola's Flow spell left on him, but there is only one way to know for certain. ]

Well then, how does it work? What do you do to access it, exactly?

[ He mirrors Stephen's pose, legs shifting to cross in front of him as he rests his hands on his knees. Yet it must require more than simple meditation and clearing of the mind, or so he would guess. ]
