Description

B-21 was founded in 2002 after a containment failure of several biological instances, and it was created for a bio hazard fighting unit. Although by 2011, it's focus had changed, they thought they could save the world with some of the instances in containment, so they tried to use force. Luckily, their attack failed, however it's rumored they are still out there, preparing. Some B-21 members did not support the cause, and those who hadn't were reassinged into the ERA, EDU. And those rumors are true. We're here, and we're ready.

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
