Van Eekhout took that question. “There’s a Forerunner structure deep underground on the outskirts of Suraka. Judging by ONI seismic scans before the reoccupation of Suraka, it matches the design of the only other known hive but . . . we believe that this structure has the potential to store hundreds of thousands of Sharquoi. A scale unlike anything we’ve ever seen. We don’t think the San’Shyuum knew it even existed. They tended to . . . misinterpret a lot about Forerunner artifacts.”
