The EN World kitten
I'm not sure which anthology that was, though I'm a tad interested in finding out now. It's worth recalling (or is it?) that Drizzt briefly appears in Brian Thomsen's novel Once Around the Realms. I suspect it's no coincidence that Thomsen was, according to James Lowder, the reason why things got so bad between TSR and Salvatore that someone else was commissioned to write Shores of Dusk.Yes, there's the general lack of cohesiveness you mentioned quite apparant with many multi author characters.
Then there's this case which is very unique since none of Salvatores characters are multi-author.
There are merely three exceptions (of which only two ever made it to print) and they all date back to a time Salvatore and TSR were in a nasty fight about his contract.
TSR wanting to demonstrate strength then took his characters and gave them to other authors. Results were Arti appearing in this series, a Drizzt short story in one of the Realms of [...] anthologies and s whole Drizzt novel (Shores of Dusk?) which was written and advertised but ultimately never published.
