Our plan is that Svenya will make an illusory wyvern, attempting to goad the ogre into fighting the real ones, and I'll stay here with her while the others go around to the other entrance to the clearing, so they're ready to attack the wyvern that the ogre doesn't go after. Of course, that plan instantly goes to shreds.
We were foolish enough to assume that the ogre would have a heart as stout as his body, but the big oaf only ran from the wyverns, nearly crushing me and Svenya without even noticing us. I shoved him off of Svenya with a crash so I could heal her, and Carmilla ran off in the commotion while the others came around the back to try and help us. With that crash though, the wyverns get curious and start shambling over, but they aren't the smartest creatures and I'm able to distract them for a while getting them to bat at an illusory person.
While we hold our positions and let the ogre run off, Svenya healing herself up and the wyverns sniffing around distracted by the lights, but Shepard is practically shaking from excitement. I reach out to try pet him like he likes, when he starts and bites me, making me lose concentration as my lights fizzle out, and one of the wyverns spots Carmilla across the clearing. They're stupid enough that I'm able to distract the other one with another light, but there's no holding back now.
As the one wyvern flies towards Carmilla, the rest of us pile up on the other, and with a flurry of valkyrian blades from Svenya it goes down faster than any of us expected. The ogre comes charging back in and gives Shepard a good wack, but it isn't long before him and the other wyvern are limp on the ground as well.
We take a few moments to salvage what we can of their bodies before retreating back to the kobold clearing for a short rest. The others said they heard the ogre talking about a 'master', one likely enough still in the forest, and we think it best to catch our breath before pressing forward.
