Walkthroughs for custom maps.

Hans C. is more likely the author of this map ("Eternal Love").

Sewa, that's right, he's the author of this map; the accompanying file (which is in the original archive) states this, and it has two names (Eternal Love / Where the Beauty). There's also another campaign with the same name, created based on it.
I'd also like to add that, since the map's author is Hans C., judging by "The Lone Knight," everything is very well thought out, and there should be an idea of how and what to use to defeat the final boss. So, if we're given the King's Undead Cloak, it's definitely not just for show; it's meant to be used. In "The Lone Knight," it's given late in the game, and I didn't manage to create many liches, but it needs to be given to a guard or soothsayer soon after for something.
