The cat snorted, and he'd get a mental image from her along the lines of '<em>don't care, head scratches.</em>'<br/><br/>The book was... dense. Fortunately, it lacked any traps that he could identify, as nothing blew up in his face, but just reading the material very nearly gave him a headache, as it was all extremely high level magical theory. From what he can interpret, though, the entire first half of the book is laying out the theory of the rune presented on the cover; how it was developed, and the various threads that lead to it. The second half moves into theoretical applications, and he gets the feeling that the author never actually tested the rune... and for good reason. It discusses the concepts the parallel worlds, and the idea that, with this rune, the 'gap between them can be bridged', also noting that the power requirements would be absolutely massive, rendering it impractical for anything short of a circle of archmages.
