I have to see THAT!
EDIT:
A strange site. "An astral mage may enter to seek treasures."
Pity it's only Astral mages, but still... 3 guys died when a Lesser Horror ate him. One Theurg survived two crossbow and a sword trap, then wounded a Lesser Horror with a Freezing Touch after his Emerald Guard bodyguards started routing, the LH flew away from him and into the path of a fleeing EG and got killed! Next turn he found a magic item (Thorn Staff...

) but a Horror killed him.
The next try, an Arch Theurg scripted to cast Smite, returned with a Soul Contract without encountering anything.
I switched to the next guy, who entered and found 1500+ gp and 40 gp. Then the enemy died of dominion-loss, as this was a 6-province tiny test map. A
cool site, wouldn't you say?
Thanks for mentioning it, tka!
