Whats a Node?
If ley lines are analogous to rivers and streams, nodes are analogous to ponds and lakes — they are “low points” where magical energy gathers. Tapping a node requires strength and skill — when he first learned how to do it, Doug called it “drinking from the firehose”, because a mage using a node is like a drain or leak — all the “pressure” built up in the node wants to rush out through him. The mage needs to be able to cast and maintain his spell while at the same time accessing and throttling the flow of power that wants to run rampant through his body.
