Digital Being: Palm Hologram Projector. This hand held unit allows the digital being to interact with other party members. In this case, the entity is assuming a lounge singer form and revealing the ancient floor plan of a facility that the dig team is about to enter. Much of the complex is perhaps collapsed or flooded, or even inhabited by warmorts. The digital being might actually be housed in the held held unit's memory chip (which is risky) or being transmitted from a CPU someplace safer.
