the first Sunday of every month,
around 8 pm realm time,
(I’m a little unsure if the time of the moonrise is affected by daylight savings time… During “summer time”, it rises between 9:30 pm and 10 pm)
you are peacefully invited to watch the moon rise,
on the cliffs south/west of Stormwind - south of Stormwind harbor, west of the Mage District.
Elixir of Tongues,
so that you can interact with the other faction.
Usually a wise and nice night elf will say some wise and nice words as the moon rises (the big one, not the small one).
