lets create party for groupfinder named "Dune"

Respawn times for these are very long right now it looks like. The best guess I have is every few hours around the 40-45 mark in the hour if anyone is curious. Have camped and they have spawned twice thus far. One was at 8:45 PM PST, the next was at 1:40 PM PST the next day. Will update.

There will be a flavor text in chat that says "A loud rumbling echoes in the distance as the northern sands begin to shift" for spawns.

EDIT: Respawn times seem to be very random as of now. Not sure if that's intentional or bugged. Iska spawned at 1:18 PM PST, and then Marzan spawned at around 1:54-55 PM PST, so not even an hour later. So my best guess would be anywhere between the :40-55 minute mark for spawns every few hours. At least I feel like that's what Blizzard would be going for.
