Just threw him up against two blind cave ogres, it wasn't pretty for either side. He started stabbing into the upper body of the first cave ogre, pierced a lung, and then pulled out, cutting off the ogre's head while only receiving some bruising. Then somehow, the second one got a hold of a wooden spear, which did some damage to my champion's cheek. with a spear lodged in his face, he stabbed the cave ogre in it's right upper arm, his longsword getting stuck in it. A shaft smack destroyed his other cheek, while the cave ogre just got the flat of a blade upside his head. The cave ogre started wrestling, and after many failed grip breaks, he started choking my champion, only to release his hold soon after. After another wooden spear stab, which my champion dodged, he cut the spear arm clean off. A few minutes of hilt smashing later and the skull caved in, my champion had beaten these menaces. Maybe I'll have him get rid of those annoying trolls a cavern layer down next, or have him assist the GCS clearing on the first layer.
In other news: The aboveground city is well under way, with ten dwarves always doing construction. Two miners are working on the 3 z-layer ditch, which will be filled with water via bucket brigade. Basements are being smoothed under each buildings right now, as I've cleared away most of the dirt layers through channeling, except a little up in the top corner around the river. My regular military is currently making a push through the huge herds of troglodytes that keep wandering in, this place has an infection with them. I got a forgotten beast that was easily handled, a massive skinless bat with a thirst for blood. Nice try, Dracula. Those little tunnels between each cavern layer have been sealed off, and I'm soon to square off each cavern layer and put small village structures in them. My champion is spelunking in the second cavern layer, killing anything he sees. Except the friendly ant men. They're permanent residents, and are on my patrol routes for protection.
