Does Vilemaw Lair prevent all forms of movement including from effects like Zenith Blade, Flash, and Ride the Wind?

Ruling: Vilemaw Lair prevents all forms of movement effects, including abilities like Zenith Blade, Flash, and Ride the Wind.

Nuances:

• Recall is not considered a move, so effects like Sett or Zhonyas can still recall units from the battlefield
• The Syren's gear effect would not work with units in Vilemaw Lair battlefield since it involves movement
