The latest updates from BGWFans on the park’s 2021 coaster project shows that they have uncovered what appears to be the layout for the coaster project. According to the description, it seems to be a multi-launch shuttle coaster, where the train will move out of the station onto a launch track, shoot forward up a hill, roll-back through the reverse-launch and up a spike, and then forward again through the launch very fast this time, over the hill and into a couple of turns before shooting up a very tall spike before rolling backwards through the whole layout and back into the station. Based on the documents, they say that it looks as if the coaster may even re-use the old Drachen Fire coaster station.
Sounds like an interesting coaster, but as a follow-up to Pathenon, which also features a multi-launch section, the design choice here is a little odd to me, as it seems a bit too similar to what the park is opening in 2020. More on this as it develops.
