"Once the queue becomes available for Crystalline Catastrophe, Vice Admirals and Brigadier Generals will see a new Reputation appear on their character status screen. Within this new Reputation, we will be periodically introducing new seasonal projects that players will be able to use to track their progress within any individual event. For the time being, only a single Project will be available, which will be focused on the Crystalline Entity, but we fully intend to make use of this Event Reputation as a central location for players to track their progress through all future seasonal events (such as the inevitable return of Q’s Winter Wonderland next holiday season).
The process for completing the project is simple: Each day that you participate in a successful defeat of the Crystalline Entity, you will be granted a single Crystal Shard. You may participate in the event as many times as you like to earn Dilithium Ore, but will only receive this special item once per day. Once the necessary number of Crystal Shards is input into the donation requirement for this project, it will automatically complete, and your reward will be available to be claimed after a few seconds wait. During the 3-week run that this queued Event is available, you will have the opportunity to earn up to 21 of these Crystal Shards, but only 14 will be required to complete the Project.
The reward for completing the project will be 50,000 Dilithium Ore, 1,000 Fleet Marks, and a unique Crystal Shard Space Non-Combat Pet. And if you gather more than 14 Crystal Shards, each additional one can be traded in for another 100 Fleet Marks, using another Event Reputation Project that will become available after the main Project is completed."
