It takes him almost no time at all to realize since he is very familiar with book spines and the way one smells, and the memory is particularly sweet to him. Istredd smiles as his fingers stroke along the cover, older than the shinier books he saw in Hayle, but he likes them old and obscure. Even the fiction. A burst of pure unfiltered love shoots through the bond and he holds the book to his chest, not unlike how he did in Nott itself.

He might not ever read this, but he also doesn't need to. Symbolically it is a vitally important text. Istredd did know where this book was and had considered looking for it sentimentally. The fact Lucifer did do exactly that makes him feel warm and fuzzy to a ridiculous degree.

Where are you?

Istredd can, as uausl, simply find him, but he prefers when Lucifer willingly tells him so he gets a head's up.
