Arcavios was one of the many planes affected by New Phyrexia's Invasion of the Multiverse. The prestigious school of Strixhaven nearly fell with most of the deans compleated and red sinew growth spreading throughout the college, but it was temporarily thwarted by the Invocation of the Founders that repelled the Phyrexian forces. In the aftermath of the invasion, the Lorehold college led the rebuilding of the Strixhaven campus.
