At first, it was easiest to guess that this was some kind of life saving relic. Perhaps it would regenerate their body before they fully died or something like that. However, only a few moments passed before Dahlia set that possibility aside. The mana being circulated didn't have the same feeling as life attributed magic; rather, what the relic was producing was more akin to the death attribute.
Her thoughts were confirmed quickly as everyone in the room watched as the soldier's limp body began to twitch and jerk in a way that very much didn't resemble life. Some attacks were directed at the corpse, but with a relic being active, everyone was hesitant. Attacking carelessly while an unknown relic was active was a surefire way for something to go wrong after all, and so because of that, no one knew what to do or how to prevent what was happening.
