It would most likely surprise anyone but his clan - and of course Kain - to learn that Rahab is not half the bookworm he appears to be. She, little shadow that she is, has never seen the Lord in the abbey's library except to research strategies from the old records. Most of the papers strewn across the large table in his rooms are reports from spies or overseers. Now that the vampires rule Nosgoth, someone needs to keep track of the resources - slaves, the birth rates of the breeding pens and so forth - and it falls to Rahab since his brothers do not seem to have a head for numbers between them. And so she watches him do complex calculations in his head and pore over strategies when they are needed - with no small amount of cursing his brothers, and muttered wishes for them to finally use their brains instead of his. When not occupied by numbers, his clan and his brothers' arguments, he keeps his skill with the spear sharp, going through the motions of fighting invisible enemies with his eyes closed. She never tires of watching this part of his routine; the sequence is never the same. Sometimes a particularly disobedient slave will find themselves subject to being hunted down as though the vampire Lord has neither fledglings to hunt for him, nor the privilege of having his meals literally brought to him on a silver platter if he so wishes.
Rahab does not notice his little shadow until one of the new slaves, a former priest, happens to notice her in her small alcove next to a dust smothered bookcase. Now the watching is a two way game. Rahab demands information from her. She points him to the records. He scowls and demands to hear it from her as the records are incomplete. She watches him do exactly as expected with the information - absolutely nothing. When she tells him that Raziel will return from the abyss, he believes her.
She watches him die, and ponders a question there is no one left to answer: Was it worth wasting such a brilliant soul?
