Talismans are temporary mobile hardpoints. They are created via the Darkness Devices of the High Lords, or sometimes naturally through great or epic deeds.
Those created by Darkness Devices last a month before they become inert. The device can set the effect radius as it wishes, usually no more than a similarly sized hardpoint's radius.
Talismans may be recharged if placed in an area with the axioms and World Laws of its home cosm, and Possibility Energy is provided by an Eternity Shard or a friendly reality-rated being who willingly gives his Possibilities to the talisman. The amount of Possibilities that must be spent is one per day, or twice that if the talisman was completely inert before being charged.
The time to recharge is twice as many days as it needs to regain. If a talisman needs to regain three days worth of charge, for example, it must recharge for six.
