So, regarding the Surviving Librarian, this is what I have so far.
@Nithyn, do you think he would be a good fit for Domnall?
A relatively older man who worked his way up, from scribe to librarian... and then Praesis was attacked. He managed to survive due to luck (and a good hiding spot).
He used to work as a translator and advisor for the magi of Praesis, but disliked it (he prefers the company of books).
Basic V&F:
Virtues: Custos, Arcane Lore, Book Learner (the reason he became a librarian to begin with was his love of books), Baccalaureus (I figure his privileged access to the library could merit the extra XP, as if he had undergone a traditional education), Minor Enchantments (a ring with the spell to create a temporary memory locus), Puissant Art of Memory.
EDIT: strike Baccalareus, that's a social status virtue (I thought it was a General one) and he should be a Custos instead. Replace it with Educated.
Flaws: Poor Memory (prone to forgetting faces not stored on the memory palace), Lame, Proud, Fear (of fire) (since the Siege. The flames created by Guillaume of Flambeau left a deep impression on him), either Flashback (the siege of Praesis) OR Lingering Injury OR Night Terrors.
Abilities: High values of Art of Memory, Profession: Librarian and Profession: Scribe. Some Praesis Lore, varied degrees of (Realm) Lore, OoH Lore, Coill Tri Lore. Code of Hermes, basic Common Law. Fluency in Latin, Gaelic and English. Old enough to have reasonable values of Charm, Etiquette and/or Folk Ken.
He can work well with most magi (mostly advising on the supernatural realms and Coill Tri), and is experient enough to recognize the Gift for what it is, so I think he could overlook @Nithyn's character Blatant Gift. Better yet, could have former ties with a ghost necromancer from Praesis (having worked a lot for the guy), making him an immediate asset for Domnall.
Still thinking of what would work best as a story flaw. Trying to avoid the "secretly responsible for the fall of Praesis" cliché, but if he worked with a necromancer before then perhaps he learned something he shouldn't from the undead.
