Sorry, but can you explain sburb? Like what do you do what is the archagent and how do you win. Thank you

Sburb is an immersive simulation that transports you into the Medium. The player’s goals are to build up their houses to each of the seven gates to reach Skaia and complete their own Denizen quests to win the grist hoards. The Space player specifically will breed frogs until they produce the Genesis Frog. On the Battlefield, which is the planet at the center of Skaia, a war is waging between the Prospitians and the Dersites. The Dersites are fated to win and the Black King will initiate the Reckoning causing all the meteors in the Veil to accelerate at Skaia. Skaia defends itself with portals, redirecting some of the meteors to Earth. The players have 24 hours to kill the Black King before the Battlefield is completely destroyed by meteors. After they defeat him they place the Genesis Frog at the center of the Battlefield and he’ll grow, eventually releasing the Vast Croak. A door underneath Skaia will appear in the shape of the logo which leads to the new universe.
