The construction of the librarians is a closely guarded secret within the Under Library, and whoever managed to entirely co-opt the process is a mystery. Libby, though, has managed to patch out any such issues within their firmware and has been slowly working on upgrading their systems since truly gaining freedom.

One of these improvements is a nanoscale factory deep inside their core, where small robots convert materials into projectiles and storing them at a minimized scale until deployed. This has greatly increased their combat ability, but it also has added a need to consume food as an easy way to access raw materials and boost their own energy levels.

Currently, Libby stores three types of missiles: cluster missiles, which are must less accurate but very destructive at a wide medium range. Long-range missiles, which are designed for targeting things precisely at a far distance. And a third is still in the prototype phase. Once the third is finished, the goal is for it to release a series of blinding lights across a battlefield, blinding enemies and providing cover for allies to escape.

Libby wishes they did not have to go this combat route as the peace of the library is truly all they desire, but with the addition of actual friends, they are no longer willing to sit back on the sidelines while those they care about are in danger.
