DESIGNATION: Crucis (AG/AV) CONTAINMENT PROTOCOLS: All containment facilities for IS-0091-B must utilize vacuum-grade insulation and maintain temperatures at or below critical substantiation levels at all times. Containment systems likewise require persistent high energy EM spectrum irradiation with a hardened, failsafe backup power connection. As IS-0091-B is visible only to its target at any given time, approved study must be conducted by a single, designated researcher. In the event of containment breach or failure, the active researcher is directed to maintain direct line of visual contact until IS-0091-B desubstantiates, then notify Gatekeeper personnel immediately. Grade 4 low-temperature protective clothing is mandated for all personnel entering IS-0091-B containment.

Although IS-0091-B exhibits behaviors akin to its phylogenetic cousin, such as only appearing initially to single viewers, the entity has many divergent characteristics. IS-0091-B is an extremophile theorized to originate in a frigid environment, and its presence has been observed to significantly affect temperature gradients in the immediate vicinity Like IS-0091-A, direct attention will cause the subject to disperse. The entity is also more resistant to a higher range of EM energies than IS-0091-A, requiring frequencies above 100KeV to desubstantiate.
