Scans of the Spiral Sector detected a massive energy spike emanating from a Wanderer-class planet identified as Tallon IV. Scout reconnaissance was immediately dispatched to the center of the spike, a land mass at heading mark 40.08.02, returning with planetary samples and atmospheric imaging. Analysis shows the energy source to be an unstable radioactive material of enormous potential. We are unable to form an accurate risk-assessment at this time, but we are unlikely to find an energy source this powerful again. Analysis will continue, but currently Tallon IV appears to be a viable secondary headquarters.
