One of ten famous Alchemists and considered a world authority on catalytics – the study of making efficient alchemy - Wilhelm Eiselstein(ヴィルヘルム・エイゼルシュタインViruherumu Eizerusyutain) was researching the “Philosopher’s Catalyst,” a legendary material that has powers comparable to the Philosopher’s Stone. When the town of Hiessgart (where he and his daughter resided) came under attack of chimeras, he brought the refugees to safety and led the efforts in building New Hiessgart.
