From Heroes of Might and Magic I to V!

All plot inconsistencies are essentially in the Chronicles. And the fact that there are characters with the same name isn't a big deal. In all parts, it was confirmed that these characters with the same name are different people (except, perhaps, for Alamar the Warlock from the lineage of the former ruler of Varna 4 and Alamar the Warlock, a supporter of Archibald; this is the only serious blunder by NWC (plot inconsistencies in the Chronicles - 3DO, not NWC)). The second Roland is one of the rulers of the Darkside of Xeen.
