Crippling Weather: Destroy all Terrains in play. Until this battle ends, no new terrains may be played. After each time this battle an action ends, bow any personalities who performed it.
Simple question. If Crippling Weather is destroyed, does the effect "no new terrains may be played" remain in effect? We have some confusion about how terrains with lasting effects like this work.

No.
http://rules.l5r.com/CE_Glossary_T#Terrain: "If a Terrain leaves play before a battleās Final Steps, its ongoing effects end, and its delayed effects will no longer be applied."

Crippling Weather isn't actually a terrain.
However, Crippling Weather also doesn't come into play, so I don't see how you would destroy it. I'm assuming Crippling Weather creates an instantaneous change.

Er. Yes. The "destroyed" bit in the original question threw me. I reckoned it had to be a Terrain, since that's the kind of strategy that does get destroyed.
Bad Rules Guy for not looking at the card! No biscuit for me!
As Crippling Weather cannot be destroyed, the original question is working under a false premise. The effect continues after it is discarded, no different from many other strategy cards.
