From Steve Jackson Games' website:
"The city is buzzing when Halmaro the Red, the head of the Merchants' Guild, organizes the greatest caravan the world has ever seen to deliver his daughter . . . and her fabulous dowry . . . to Ein Arris for her wedding. There is a wealth of opportunity for resourceful adventurers whose wits are as keen as their swords -- are you one of them?
Caravan to Ein Arris was originally published in the GURPS Basic Set, in the pre-revision Third Edition. It was out of print for years, then brought back in PDF form. And now, it's been completely updated for the Fourth Edition of GURPS!
Ein Arris has always been a wonderful introductory adventure for the GURPS system, and now it's doing it again for Fourth Edition. And best of all . . . it's free! So fire up your computer and give it a spin, and take the Caravan to Ein Arris!"
