Old school encyclopedia game?

When I was younger my sister and I used to play this educational board game-like game on an encyclopedia disc. There were two discs, one had the actual encyclopedia on it and the other had this game and a video, if I remember correctly.

The game was like, a character select thing of different women and men - some warriors, then you were shown the game board. You had to roll the dice and you got to select where to move. You had to collect the different coloured orbs and the questions were all about like history and geography, depending on where you went. The different places were like a forest, temple, observation thing and some other stuff. Sometimes you would land on a square and a scary imp thing would come up and take one of your orbs, other times you would land on a good one and a fairy thing would come up and give you an extra orb. Once you had all the orbs, you had to go to the main temple and if you got the question correct, you won.

After all that, all I need to know is WHAT IS THE NAME OF THE ENCYCLOPEDIA IT CAME WITH!!?!?! We've been trying to think of it for the past few hours and we're getting frustrated because we can't find it on Google either. Please help!!

I'm pretty sure we used to play it on windows 98 or 2000... I dunno if that helps.

Thanks in advance!
