oh yea and its magic.. so if you want to say it shouldent work in doors.. then you should also say, it shouldent work at all.. magic isent real!
Besides, would a dingy little building stop a gods blessing? Or would to withhold the call of nature to a druid?
as the metor swarm, i dont think its actually comming from space.. there just magicly apperaing.. like fireballs just appear, you dont like need a match or something to start a fireball.
