Truth be told, it hadn't really been anything done intentionally, for all that he'd heard of the TV realm from both Even and Aeleus, with varying shades of warnings. He'd seen Even's new eyes, after all, and when his emotions weren't getting the better of him he recognized that a world with such terrors as that was not one to be visited lightly.

On the other hand, even his Lexicon needed periodic cleanings. Even information became less relevant over time and so things needed to be removed or shuffled off to better places and cross-referenced appropriately. Of course, this requires that he actually know what the various things are or can do, and so when he finds a long forgotten teleport spell hidden away in the pages of his Lexicon it only seems natural that he try out.

Needless to say, he's as surprised as anyone when it actually works and even more surprised when it drops him off somewhere he doesn't actually. And this, of course, means that he might as well explore. It doesn't look like anywhere immediately harmful, after all, and he does still have his lexicon so it's hardly like he's defenseless.
