Anybody who plays the chinese server can confirm if this is really only for 7 days? It seems they had this event in May 2019 ( they messed up translating and only did it on 1 of the quests). For us it says November 6th - 13th.
Confirmed rewards so far are:
5 Nebula Dust Orbs
1 War Avatar Pack S
1 Glyph Pack lvl 2
Would be nice if they had this forever and not just a timed limited quest...
