Quantum Realms

After grabbing the Paragon blade you dive into the portal to face what's on the other side, to your surprise its a chamber, vacant of all life. Five walkways extend to 5 different Portals, each one lit with a color, an indicator maybe? Unsure of what to make of the room, you approach the center of the room with the glowing sphere, the portal closes behind you, no way back, only way back is forward.
