I stood in a straight line towards one plant ("armed" something that are surrounding the tree). Then I cast a stun spell to knock the "flammable rune" over top of each one, some you have to use fire spell to make it bigger, some you have to use ice spell to make the rune smaller. If the rune is in the correct position it will give you a message (like not strong enough or too unruly... something like that). It gives you a yellow message when you destroy one of them. Repeat steps with each plant, it takes some practice but it does work, patience here because sometimes you knock it past the plants, run to the other side and try to knock the rune back over top of the plant. After you destroy all the plants a whirling wind surrounds the trees/rocks, go back inside the circle and cast a wolf spell on yourself. There is a "Great Wolf" that appears, read text that appears in a separate box. Hail the wolf, until you get a message with some kind of (text) and /say whatever the text cue is. Do this until it says you join the pack of wolves and run with them. They take you to kill poachers as a pack. I cast mire thorns, stun, fire spells on poachers. They hit pretty hard, so I stayed a distance away, and the pack will chase them as the poacher chases you. Once all the poachers are dead. The wolves run back towards the tree again, but give you the message to invis yourself to not been seen. Then after you are camo sneak close enough to hear the conversation of a Mysterous ward, Jale... (from SK), and 2 unkempt druid/rangers. After their text is finished the 2 unkempts will come after you. They hit hard & shoot arrows with quick damage. Dark blue to my level 70 druid. This is as far as I have made it. Had to run off, heal myself, and camp. Was going to die lol. You have like 6 hours to complete the event. Not sure how much more there is before its over. I never received the dolomite on my curser or inventory to this point.
Update: I rooted one unkempt while I kited/dotted the other one. After they were dead, found the secret council in the SW corner of the zone. There is a named bear, 2 snakes, 2 griffons, 2 wolves, a lion & lioness, a bear, and 2 panthers. Hail the named bear follow text. He tells you to pick and choose who you think is the corruptor. Then tar an animal in the council /say accuse, then it attacks you. I ended up killing half the council, I picked a griffon and it turned into Jale Phlintoes. He was yellow to me and I had like 20 minutes to finish the event. I used spell Spore Spiral to root/snare him & dotted him. When I finally had him around 31% or so (also had less than 5 minutes to finish) this ancient bear appeared (looks like the ones in the Great Divide) and it finished killing Jale off.
