If you already have Brauer Academy on your map, it's easiest to start from there, via the south-west exit. Just follow the red path on the map, provided at the top of this page, to each of the three volunteers. Head west through point 2 (go past Leiber) to point 1, pickup Klaus, return to point 2 and then collect Leiber. Travel on to point 3 and gather Ex-Redempter Berta, then continue to the end of the red path and speak to Baron Mirek Vasburg to complete the quest and gain access to the Eternal Grove.
