Heralt did not react to the remark, and started explaining. "Our task is simple. To keep an eye out for anyone who makes contact with Otherworlders. Ideally, we bring them back to our side, but if a need arises, we take drastic measures to keep Alvox clear of foreign influences."
"As for the Otherworlders themselves?" Endra asked.
"Due to the influence of mana, Otherworlders cannot survive without the various apparatuses that keep them alive. So, distinguishing them isn't that hard when they decide to come out into the open. What's hard is finding their hidden bases and the people they've reached out to."
"I saw them using some Cloaking Device on their bodies, though? Even some mages had them."
