Data-Shard of the Architect

A crystalline data-shard that hums with a faint, alien signal. While you hold it, you have advantage on Intelligence (Arcana) checks made to understand artificial intelligences, post-human consciousnesses, or pre-Collapse code. Once per long rest, you can use an action to replay a fragment of the signal, granting you advantage on one Intelligence (Investigation) check made within the next minute. The shard is also the key to Sector 7.
