Best Served Cold is my favourite Abercrombie book; I haven't read many of them, mind you, but I read the First Law trilogy and while that was very nice (I say nice on purpose, even though it's quite dark!), BSC is a cut above for my taste.
My concept is solidifying as
Darios the Black
a halfling necromancer (Warlock) whose tale, even after he got captured, still inspired followers to raise a plague of undead, causing periodic trouble in the kingdom.
So the Petals cunningly ran a smear campaign, decrying his achievements, until they got him re-baptized "the Cowardly Necrophiliac" (among other unflattering titles), which did wonders to stop the romantic attrait of emulating him.
He would now very much like to erase that shameful moniker.
...The Cowardly part is not even completely wrong, since he tends to remain Invisible and let his minions do the work for him. He can also make new undead recruits mid-combat from the corpses of the fallen, no matter which side they were on.
But if I get accepted in Petals, I'll likely drop this one.
