The Shimmering Crystal (Alliance)

Updated macro for The War Within and beyond to check whether you’ve completed the weekly Timewalking quest, for both Horde and Alliance and for all different Timewalking campaigns. If all the text appears red, you haven't completed this week's quest yet.

Alliance:
/run a={{"Classic",43117},{"BC",0},{"WotLK",5},{"Cata",619},{"MoP",5395},{"WoD",15330},{"Legion",24542},{"BfA",49054}}for i=1,#a do n,o=a[1],a[2]print("\124cFF"..(C_QuestLog.IsQuestFlaggedCompleted(40168+o)and"00FF00"or"c51a20")..n.."\124r")end
Horde:
/run a={{"Classic",43117},{"BC",0},{"WotLK",5},{"Cata",618},{"MoP",5395},{"WoD",15330},{"Legion",24542},{"BfA",49055}}for i=1,#a do n,o=a[1],a[2]print("\124cFF"..(C_QuestLog.IsQuestFlaggedCompleted(40168+o)and"00FF00"or"c51a20")..n.."\124r")end

Teleport to Stormwind, go to the Ashran portal, fly to the spot marked on the map.

You can check whether you completed this quest with:

# Alliance
/script print(IsQuestFlaggedCompleted(55498))
# Alliance with pretty coloured output
/run print(format("%s: %s","WoD",IsQuestFlaggedCompleted(55498) and "\124cff00ff00Yes" or "\124cffff0000No"))

# Horde
/script print(IsQuestFlaggedCompleted(55499))
# Horde with pretty coloured output
/run print(format("%s: %s","WoD",IsQuestFlaggedCompleted(55499) and "\124cff00ff00Yes" or "\124cffff0000No"))


You can combine the lines in a macro as you see fit.
(Lines starting with '#' are merely comments for convenience and can be safely skipped when copypasting to an in-game macro.)
