From the outside, floating in space, it's an escape pod. Not a known configuration of escape pod, but there's a certain look to escape pods, yes?
However, sensors show it's outputting more power than a Wolf-Rayet star. That alone should be a reason to investigate...
Thanks to a catastrophic malfunction, this escape pod comes from thousands of years in the future of the PCs. From the pod, there are links to different parts of spacetime, allowing exploration.
