What is the obelisk

You can get to it thru a Celestial Portal, which spawns from a Celestial Orb.
Unsure on how to trigger it, but in chat it'll say something along the lines of, "a celestial orb has appeared" and once trigger and finish the teleporter, the portal will spawn.
Obelisk is what allows you to unlock the character, Mercenary. You have to "Obliterate" yourself to do so, which will end your run, but you only need to do it once. After that, if you ever end up there again, just walk up to the Obelisk, then walk back down to the right where there will be a portal back.
