Hm, I'll search for it the next time I'm around my local bookstore.
I myself have plenty of time on my hands, as well, though it's still not nearly enough to accomplish all that I want to accomplish in a day.
And no, I'm afraid that it isn't Ishamael, though I did happen to have a signature and avatar using Ishamael, though:
'Twas fashioned by the ever-so-talented fal'Cie, if you're curious.
My current set, however, features Artemis Entreri, an antagonist from The Legend of Drizzt, considered by many to be the drow's rival; the man is a ruthless, passionless killer, who spent his entire life honing his skills so as to become the ultimate weapon. However, later on in the series, Drizzt eventually overcomes his fear of Entreri and defeats him with ease, and it is only then that both he and the assassin realize that Entreri's entire life so far has been hollow, with no true purpose or meaning to it at all other than to kill, as he only uses the bounties reaped from his assassinations to purchase necessities. After realizing that his life was, essentially, meaningless, the assassin spent much of the remainder of his life focusing on exacting revenge on Drizzt, for making that awful truth known to him. Afterwards, though, much afterwards, the man focuses on making the best out of his remaining life, and succeeds to an extent.
Forgive me; I tend to rant at times, when the topic interests me.
