The Laboratory of Mardivas

This quest summons the mobs needed for Periodic Destruction which is a part of the meta Undersea Usurper.

The mobs seem to drop ~2-3 [currency=1721] and the final quest turn in giving 5 [currency=1721]. If you are unsure if you have done it this week you can copy and paste this into your chat log. If "true" is returned it has been completed. If it states "false" then the quest hasn't been done. /script print(IsQuestFlaggedCompleted(55121)).

Super frustrating trying to get there with all the current overtuning. Good luck.

It's looking like every one of these summons has additional items they can drop. I believe all of these models can be found elsewhere, like in Arcane Chests or from Nazjatar rares. But this is still a source for a few interesting pieces of transmog, or at the very least, a few interesting recolors, and allows you to farm specific models by choosing specific elementals every week.

The elementals also have a chance to drop the various 'tool' items from Nazjatar. ([item=167077], [item=167059], [item=166888], and [item=167012])
