On 28th August 2019 players were given an apology for all the recent downtime in the shape of a reward cache called ‘Anvil of the Storm Cache’
The reward cache is found in the claim box in the upper right of the rift store.
The reward cache contains….

• 6500 Celestial Remnants – Looted straight away by the character that opens the Anvil of the Storm Cache. Make sure you open the cache on a character that needs Celestial Remnants.
