I love hearing about other peoples' games. Most interesting.
Our first game was a disaster.
We were tasked to seek out an area outside of the city where the orc army (led by their half-orc leader) had stationed a nexus for magic energy that was one of three that had been used to rain down a magic bolt that completely destroyed an entire building.
Wandering through the field (using an invisibility sphere) we passed through another invisibility sphere, which revealed a huge orc camp, with over 100 orcs, and a giant in it. Casting fly on the rogue, he was able to look through the tents and find the source of the magic nexus. Meanwhile, the leader of the Orc camp is here, along with his 12 bodyguards. We overhear a conversation between the wizards running the nexus, and the leader that there is some kind of disagreement. The wizards are mercenaries, and evil, and the leader doesn't want to allow them to use the magic in the nexus at will. So, the cleric in our party thinks he can start up some kind of fight between the leader and the wizards by posing as one of them (he's the same race as the wizards - Egyptian, basically). His plan backfires, as the leader sees our cleric, and then confronts the entire party, as he (so we found out) was able to see invisible creatures, through his magic helmet.
Amazingly enough, he let us all go, after extracting some information from us, but our mission was a failure. My friend (playing the cleric) and I commented later that, by rights, the entire party should have died (at least those who would have been unable to escape), but the DM must have been in a good mood.
