The mandates of house Orien will also raise the cost of any long range teleportation items by 25%, unless a party member or contact thereof is favored by the house.<br/><br/>The following sorts of magical effects also tend to have their costs raised by house monopoly: Major/Minor Creation, Fabricate, Control Weather (and other spells which change the weather in an entire region), Sending and other overland communication spells.<br/><br/>In most of these cases, the cost increase is because the dragonmarked houses have a major magical artifact or system which replicates the spell effect, and they want to restrict the availability of such spell effects so people will use their services.
