Sacred Haven of Debauchery

I was playing through the first campaign of the original HoMM IV. At the very beginning, I hired two heroes and played with them throughout all the scenarios. And the main hero (Lord Lysander) of the scenario was always somewhere hiding and rarely participated in battles, only because he was less appealing to me than those two. When I reached the end of the campaign, it turned out that Lysander had to fight one-on-one with the "main villain." And so, he, completely untrained, enters the battle and... dies.
