Thank you! I apologize for my NA-centric posting. I have edited my post above and will include Remulos in the future.
Interestingly enough people said that could not be done in the past but Aggrend put some info out a Classic Era discord that says they seem to have conquered that mountain. Maybe we could resume asking for all PVP to be connected to each other in Era. Same with PVE. Reference is here (thanks again, Woddisc):
