Today, a rather convoluted series of syncs -- taking me from the "tulip tree," Liriodendrom tulipifera, to the Luria-dendron of the qlippoth -- led me to the Lurianic terms Olam ha-Tohu (World of Chaos) and Olam ha-Tikkun (World of Rectification) -- and the latter is pretty clearly my own personal Éliphas Lévi. William becomes Olam (also transliterated Gholam; cf. Guillaume), and Tychonievich (a Ukrainian patronymic from the personal name Tikhon) becomes Tikkun. I guess Olam ben-Tikkun would be the proper form.
One major drawback is the similarity to tikkun olam, which is the Jewish term for Leftist "social justice."
