Red Harp

Red Harps are an object in Marrow.

Description
Red harps exist in the Laboratories, Sewage, and Malignancy. They make a strumming sound when struck with a weapon and usually have Lumen Flies hovering around them. Striking a Red Harp is necessary to enter the Laboratories, and striking several Red Harps within the Laboratories and Malignancy will cause the Lumen Flies to either die, or light up with a specific color to be used as a code for the Resonant Orb.
