Says it better than I ever could. Void Relics are basically the new Void Keys.

[PsychedelicSnake]

1. Key have been replaced with Relics, which more or less serve a similar function. You can view what Relics you have in the Void Relic Segment aboard your ship, in a corner near the Arsenal. To unlock this Segment, you have to complete the Mars Junction on Earth.
2. Groups are typically formed by people looking for others that have the same kind of Relics they do. For example, someone looking to grab a Mag Blueprint will be looking for others that have the same Relic that drops it.
3. You can invite other players that don't have a Relic, but these players won't give you the extra opportunity to choose what you want from the end-of-mission rewards.
4. You can check where to find Relics in the Codex, under the Relics & Arcanes section. Each Relic lists what is dropped and where they are dropped.

EDIT: More Stuff

• You get prime gear by using Void Relics in Fissure Missions, which show up as special alerts that are always active. 
• To unlock a Relic in these Fissure Missions, you must collect 10 Reactant, which are dropped by Corrupted enemies that are spawned and created in-mission.
• When you collect 10 Reactant, the Relic is unlocked and you get a certain number of Void Traces.
• At the end of the mission, you will see a new screen showing what each squad member got from their Relics (assuming they both brought a Relic and got enough Reactant themselves). You can then choose from up to four different rewards.
• The Void Traces you got from the mission can then be used at the Void Relic Segment to upgrade any Relics you have, which both decrease the chances of you getting common items and increase the chances of getting rare items.
