Hi,
I've got a little question. Are there any merchants in this game? I'm in the throggish temple now and I'm carrying a couple of unimportant stuff, that makes my inventory huge and pretty annoying. Is there any chance to sell those things and buy a new equipment? Or should I simply throw it away? Thanks for the answers.
Btw, this is absolutely fantastic game. I grew up on these games, but Stonekeep missed me, so I've geen playing it for the first time in these days. And after many years, it is still very playable game, even without the element of nostalgy on my side.

As I recall there are no merchants. I am a collector when it comes to ingame items so i never throw anything away unless I have too. I think you can use the page up and down keys to move more quickly through the inventory but it has been a long time since I played this game last so I could be wrong.

I do not recall any merchants, but as Gator_man says, you can move up and down quickly and also stack items.

There is a dwarven merchant who sells you items for gold coins, but there's no way to sell items in this game. Rather than get rid of anything, I'd take a few minutes to empty your inventory and refill it in a way that makes sense.
Also yes, pageup and pagedown help A LOT.
