Children of White Blood

Halloween is a mercenary who tries to stay out of any wars. But one day, going into the world where his beloved lives, he gets pulled into a confrontation between powerful mages and monsters. From now on, he holds the key to all doors; behind his back are two armies. To survive, he will have to choose one side and deal with the demons of his past.

Meanwhile, representatives of the strongest non-humans meet for negotiations in a sealed world. At first everything goes well, but soon two diplomats die, and one disappears without a trace—now several monsters are trapped in a single tower until the culprit is found, and it turns out to be one of them.
