Easter eggs in Heroes.

Here are some interesting things:
1. The Fire Lake; it looks like it was made in the editor, and most importantly, it says that you can recruit phoenixes and firebirds. Phoenixes are understandable, but what about firebirds...?
2. Why is the tank passable?
3 and 4. I've never seen black knights before. Only death knights. You can compare them (black knights have the same abilities, but without the death strike).
5 and 6. Frieda is an artifact; that's cool. It's a shame it doesn't do anything.
6. For those interested in that cyclops that doesn't look very alive, it's a mod for SnowApe, the Dead Cyclops (those who played Darkmessian will be more familiar with it) (thanks to Archdemon and those who downloaded it from him).
7. There's some strange city where you can't build anything (even in the editor, it doesn't show any buildings ). As soon as you enter it, the game crashes.
Ugh, I've started rambling. Well, you can't argue with what's written by the computer, not even with a chainsaw.
