Children of the Divine Order
Doorway (Often called Portal) magic deals with physical and non physical gateways. It can be used to bar doors (and windows) or open them. However it can also linked one gateway with another, allowing near instant transportation between locations. The main limitation is the power of the caster. The most powerful of adepts can create portals without a physical gateway anchoring them.
Portal magic can overcome obstacles involving doors and also allow you to link two gateways together.
Create an Advantage
Portal magic can be used to create certain kinds of advantages like ‘door that cannot be opened’ as well as ‘door that cannot be closed’.
Portal magic is not suitable to attack.
Portal magic in very particular situations can be used for defense, though is not usually worth it.
