Archon's Forge is a new Player Triggered Event.
Respawn Vs. Revive
You can be revived without penalty. Just watch the timer.
Any player that dies during the Events then they will need to "buy back in" if they respawn. You can complete particular objects or spend certain currencies. If all Guardians leave the arena for more than a few seconds, then the event will fail. Your Offering is still considered expended.
Triggering Archron's Forge
There is a console in the upper area. Approach and interact with it to start the Trial. Each event has a 5 minute timer. You must kill the boss before the timer expires to complete the event and receive its rewards.
There are events for each of the different Splicer units.
