@socajunkie: Thanks for your reply.You are right, they are a mixed bunch. And there are some relatively mid-level hitters among them.However, my interest was more centered on how these characters, most some very different worlds and realities, would adapt to their new circumstances, their fellow "travelers", and whether they would be able to overcome their differences and work together in order to survive long enough to find a way back home for each of them.And then of course there are the individual questions regarding each of them. For example: Can the Riordanverse's Celestial Bronze affect the Ringwraiths/Nazgul? Would the magical abilities of the group's mages/witches be affected by their new environment? And if so, how? Etc.There's also the question of whether they'd be accepted by the nations allied against Sauron, and to what extent.
